Abstract
In a backlight module of a display apparatus, the base substrate is a flat plate structure, so that the backlight module can be prevented from being subjected to a bending internal stress, thereby avoiding a damage to the backlight module and ensuring a yield of the display apparatus. At the same time, the difference of backlight brightness provided by the backlight module to different regions of the display panel is smaller, so that brightness uniformity of different regions of the display apparatus can be ensured, and a display effect of the display apparatus is better.
