Abstract
A light source module, a liquid crystal display device, and a display apparatus are provided. The light source module disposes a plurality of micro structures disposed at intervals on a light guide surface of a light guide plate and disposes a sum of areas of the micro structures on an unit area on the light guide surface gradually increasing from a light incident side to a light exiting side, which can improve uniformity of light exiting brightness of each region of the light guide plate.
