摘要： A light guide plate comprises a transparent light guide plate body; and a plurality of reflection sheets disposed inside the light guide plate body adjacent to a bottom surface of the light guide plate body, wherein a surface of the reflection sheet away from the bottom surface is configured as a reflection surface, regions of the light guide plate body except the reflection sheets are configured as light transmission regions, and the light transmission regions and the reflection sheets are alternately arranged. Since the reflection sheets are provided inside the light guide plate body, the reflection sheet reflects the light which is directed from the one surface and passes through the display panel, and prevents the light, which is directed from the other surface of the display apparatus, from passing through the display panel and interfering with the normal display of the one surface. In this way, the display apparatus can achieve the double-surface display.
