摘要：
A light guide plate includes a first optical member having a first light path-changing portion to separate a first light portion and a second light portion from a light, and a second optical member having a second light path-changing portion corresponding to the first light path-changing portion. The first optical member has a first refractive index against the first light portion of the light and a second refractive index against the second light portion of the light, and the second optical member has the first refractive index against the first and second light portions. Thus, brightness and brightness uniformity of an image displayed on a display apparatus may be improved, and a number of parts of the display apparatus may be reduced.
