What is claimed is: 1. A display apparatus having a casing in which an opening part is formed, comprising: a liquid crystal display panel that is supported by the casing so that an image can be displayed through an opening part; a backlight unit that is provided behind the liquid crystal display panel and has a light source that emits light; a shield cover that is provided behind the backlight unit and is supported by at least one of the backlight unit and the casing; a cooling fan unit that is combined with the shield cover and supplies cooling air to the backlight unit, and wherein the cooling fan unit comprises a cooling fan and a fan cover that has one side provided with a first combining part combined with the cooling fan and the other side provided with a second combining part combined with the shield cover. 2. The display apparatus according to claim 1, wherein the light source comprises light emitting diodes (LEDs). 3. The display apparatus according to claim 1, wherein the shield cover is provided with a fan support that supports the cooling fan unit, the fan support being distanced from the casing and being formed at a position adjacent to the backlight unit. 4. The display apparatus according to claim 3, wherein the fan support is formed at a central lower portion of the shield cover. 5. The display apparatus according to claim 1, wherein the casing and the shield cover are provided with a plurality of air slits through which air generated by the cooling fan unit comes in and out. 6. The display apparatus according to claim 1, wherein the first combining part comprises: a first support that supports the cooling fan and the fan cover; and a first joining member that joins the cooling fan with the fan cover. 7. The display apparatus according to claim 6, wherein the first combining part further comprises a first vibration absorption member that is disposed between a plurality of the first supports and absorbs vibration generated from the cooling fan. 8. The display apparatus according to claim 1, wherein the second combining part comprises: a second support that supports the fan cover and the shield cover mutually; and a second joining member that joins the fan cover with the shield cover. 9. The display apparatus according to claim 8, wherein the second combining part further comprises a second vibration absorption member that is disposed between a plurality of second supports and absorbs vibration generated from the cooling fan. 10. The display apparatus according to claim 8, wherein each of the first support and the second support is provided plural in number. 11. The display apparatus according to claim 8, wherein each of the first joining member and the second joining member comprises a screw.
