What is claimed is: 1. A display device, comprising: a substrate on which an array of interferometric optical modulators is formed; a recessed non-transparent backplater; and a patterned spacer disposed between the substrate and the backplate to form a package, wherein the spacer circumscribes the array and prevents the external environment from entering the package. 2. The display device of claim 1, wherein the patterned spacer is formed on thebackplate. 3. The display device of claim 1, wherein the patterned spacer comprises a photoresist. 4. The display device of claim 3, wherein the photoresist is an epoxy-based photoresist. 5. The display device of claim 1, wherein the substrate comprises a transparent portion, and an image formed on the array of interferometric optical modulators is viewable through the substrate. 6. The display device of claim 5, wherein the substrate comprises glass. 7. The display device of claim 1, wherein the display device further comprises a desiccant inside the package. 8. The display device of claim 7, wherein the desiccant is calcium oxide. 9. The display device of claim 1, wherein the display device further comprises an adhesive disposed between the spacer and the substrate. 10. A method for fabricating a display device comprising: obtaining a substrate on which an array of interferometric optical modulators is formed; obtaining a recessed non-transparent backplate; forming a spacer by patterning, wherein said spacer is configured to circumscribe the array and prevent the external environment from contacting the array; and assembling the substrate, backplate, and spacer to provide the display device. 11. The method of claim 10, wherein the patterned spacer is formed on the backplate. 12. The method of claim 10, wherein the patterned spacer comprises a photoresist. 13. The method of claim 10, wherein the patterned spacer is formed using a mask. 14. The method of claim 10, wherein the substrate comprises a transparent portion, and an image formed on the array of interferometric optical modulators is viewable through the substrate. 15. The method of claim 10, wherein the substrate comprises glass. 16. The method of claim 10, wherein the display device further comprises an adhesive disposed between the spacer and the substrate. 17. A display device fabricated by a method comprising: obtaining a substrate on which an array of interferometric modulators is formed; obtaining a recessed non-transparent backplate; forming a spacer by patterning, wherein said spacer is configured to circumscribe the array and prevent the external environment from contacting the array; and assembling the substrate, backplate, and spacer to provide the display device. 18. The display device of claim 17, wherein the patterned spacer is formed on the backplate. 19. The display device of claim 17, wherein the patterned spacer comprises a photoresist. 20. The display device of claim 17, wherein the patterned spacer is formed using a mask. 21. The display device of claim 17, wherein the substrate comprises a transparent portion, and an image formed on the array of interferometric optical modulators is viewable through the substrate. 22. The display device of claim 17, wherein the substrate comprises glass. 23. The display device of claim 17, wherein the display device further comprises an adhesive, disposed between the spacer and the substrate.
