The display module as set forth in claim 8 further comprising second channel means in said third and fourth opposed frame members, said second channel means for securing portions of display members. 10. The display module as set forth in claim 8 wherein said retention members comprise a plurality of projecting finger members projecting outwardly substantially perpendicular to the plane of said frame. 11. The display module as set forth in claim 8 wherein said retention members comprise a first elongated set of engagement fingers positioned along the length of said first frame member and a second elongated set of engagement finger members positioned along the length of said second frame member. 12. The display device as set forth in claim 8 wherein said mating male and female connection members comprise male connection members on said retention members and female connection members on said divider members. 13. The display device as set forth in claim 8 wherein each of said divider members has a rearwardly extending female connection member which is adapted to be releasably engaged with at least one male connection member. 14. The display device as set forth in claim 13 wherein each of said divider members has a pair of rearwardly extending leg members forming said female connection member. 15. An illuminated display device comprising: a housing; at least one lighting source positioned in said housing for projecting light through an opening in said housing; and at least one display module removably disposed within said opening in said housing, said display module comprising a generally rectangular frame assembled from a plurality of frame members connected together at their ends, said frame members comprising first and second opposed, spaced-apart, vertically disposed, elongated upright frame members and third and fourth opposed, spaced-apart, horizontally disposed, elongate cross frame members, said upright and cross frame members lying in a plane when assembled together to form said frame, a plurality of retention members secured on said first and second opposed frame members, a plurality of horizontally disposed, vertically spaced-apart elongate divider members for supporting between adjacent pairs of divider members one or more display members, each of said divider members being individually removably secured to the frame only on their respective ends by opposed retention members by movement of said ends of said divider members toward and away from said retention members in a direction generally perpendicular to the plane defined by the frame, wherein said divider members are only secured in the frame by said retention members and may be secured to or removed from the frame while the frame is disposed within the opening in the housing, said divider members being held in place by said retention members by mating male and female connection members; first channel means in said divider members for securing portions of display members, second channel means in said third and fourth opposed cross frame members, said second channel means for securing portions of display members, and a plurality of display members positioned between opposed sets of channel means, said display members having translucent portions thereon, wherein said divider members and display members can be removed and replaced in said frame without disassembly of any frame members or translucent members; and wher ein said display members allow light from said light means to be projected therethrough and may be provided in various vertical dimensions in order to be positioned on said frame between any opposed set of channel means. 16. The display device as set forth in claim 15 wherein said mating male and female connection members comprise male connection members on said retention members and female connection members on said divider members. 17. A method to assembling an illuminated display device comprising the steps of: providing a display device housing; positioning at least one lighting source within said housing and attaching the lighting source thereto so as to project light through a portion of said housing; and providing at least one assembled display module by the steps of: assembling first and second opposed vertically disposed frame members and third and fourth opposed horizontally disposed frame members so as to form a generally rectangular frame defining a plane, said third and fourth opposed frame members each including channel means for securing portions of display members, securing a plurality of retention members on said first and second opposed frame members, and individually removably securing by means of their ends only a plurality of horizontally disposed elongate divider members on said frame by opposed retention members in a direction intersecting the plane defined by the frame, wherein said divider members are only secured in the frame by said retention members, may be removed from or secured to the frame while the frame is disposed within the housing and wherein said divider members include channel means for securing portions of display members, said divider members being held in place by said retention members by mating male and female connection members; securing the display module within an opening in the housing; and inserting a plurality of display members between the opposed sets of channel means while the display module is secured within the housing opening; wherein said divider members and display members can be removed and replaced in said frame without disassembly of any frame members or translucent members. 18. The method as set forth in claim 17 wherein said mating male and female connection members comprise male connection members on said retention members and female connection members on said divider members.
