An LCD panel applied to a curved screen includes display sections and a black matrix layer. The black matrix layer is used for adjusting an area of the primary sub-pixel and an area of the secondary sub-pixel in each of display section, so that an area ratio of the secondary sub-pixel to the primary sub-pixel in the first display section equals to an area ratio of the secondary sub-pixel to the primary sub-pixel in the central display section, an area ratio of the secondary sub-pixel to the primary sub-pixel in the second display section is greater than that of the secondary sub-pixel to the primary sub-pixel in the first display section, an area of the primary sub-pixel in the central display section is lower than that of the primary sub-pixel in the first display section. Therefore, brightness and quality of the curved screen on image display are improved.
