The cooling apparatus according to claim 1, wherein the air outlet of the back cover is formed on an upper peripheral portion of the back cover. 8. The cooling apparatus according to claim 1, wherein the air inlet of the back cover is formed on a lower peripheral portion of the back cover. 9. A cooling apparatus for a flat display device, comprising: a flat display module; a front cover supporting a front portion of the flat display module; a back cover supporting a rear portion of the flat display module; an air inlet formed on the back cover to allow external air to be introduced into the back cover; an air outlet formed on the back cover to exhaust the air introduced; and a cross-flow fan disposed inside the back cover and aligned with the air outlet; and an air outlet channel of the cross-flow fan aligned with the air outlet formed on the back cover, wherein a blade installation angle of the cross-flow fan is 24.2��1.5��. 10. The cooling apparatus according to claim 9, wherein the cross-flow fan has a scroll extreme end angle of 30��, a scroll radius of 32 mm, a scroll outlet angle of 40��, a stabilizer installation angle of 80��, a tip radius of 10 mm, and a stabilizer dispersion angle of 10��. 11. The cooling apparatus according to claim 9, wherein a maximum camber amount of a blade of the cross-flow fan is 10��3%. 12. The cooling apparatus according to claim 9, wherein a solidity of a blade of the cross-flow fan is 0.8��0.1. 13. The cooling apparatus according to claim 9, wherein the number of blades of the cross-flow fan is 20��2. 14. The cooling apparatus according to claim 9, wherein the cross-flow fan rotates clockwise when it is viewed from a right side of the flat display device. 15. The cooling apparatus according to claim 9, wherein the air outlet of the back cover is formed on an upper peripheral portion of the back cover. 16. The cooling apparatus according to claim 9, wherein the air inlet of the back cover is formed on a lower peripheral portion of the back cover. 17. A flat display device comprising: a flat display module; an air inlet for introducing external air into the display device; an air outlet for exhausting inner air of the display device; and a cross-flow fan disposed inside the flat display device to expel the inner air, wherein the cross-flow fan has a blade installation angle of 24.2��1.5�� and a ratio of an inner diameter of the cross-flow fan to an outer diameter of the cross-flow fan of 0.69��0.03. 18. The flat display device according to claim 17, wherein a maximum camber amount of a blade of the cross-flow fan is 10��3%. 19. The cooling apparatus according to claim 17, wherein a solidity of a blade of the cross-flow fan is 0.8��0.1.
