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.

摘要： A diffusing reflective polarizing film has a liquid crystal film and a diffusing layer. The liquid crystal film includes a cholesteric liquid crystal diffusely reflecting a first component of a light substantially in parallel with a twisted axis of the cholesteric liquid crystal and transmitting a second component of the light different from the first component. The diffusing layer is attached to the liquid crystal layer to diffuse light from the liquid crystal layer. Thus, the diffusely reflective polarizing film may improve brightness uniformity, thereby preventing a warping phenomenon of the diffusely reflective polarizing film.
