Abstract: A light guide plate including a light emitting surface, a bottom surface, a light incident surface, multiple protrusion structures, and multiple grooves is provided. The light incident surface is connected between the light emitting surface and the bottom surface. The protrusion structures are disposed along a first direction and extend toward a second direction. The protrusion structures have a light condensing angle along the first direction, and the light condensing angle ranges from 10 degrees to 40 degrees. The grooves are disposed in the protrusion structures of the light guide plate. The grooves extend toward the first direction. The protrusion structures have a light receiving surface that defines each groove and is closer to the light incident surface. An angle between the light receiving surface and the bottom surface ranges from 35 degrees to 65 degrees. A display apparatus adopting the light guide plate is also provided.

Abstract: A backlight module includes a light guide plate, a light source, an optical film, and a prism sheet. The optical film includes a first substrate having opposite first and second surfaces and multiple optical microstructures disposed on the second surface and each having a first light receiving surface away from a light incident surface. The prism sheet is located on a side of the second surface of the first substrate. The prism sheet includes a second substrate having opposite third and fourth surfaces and multiple prism structures disposed on the fourth surface and each having a second light receiving surface away from the light incident surface. A first angle between the first light receiving surface and the second surface is different from a second angle between the second light receiving surface and the fourth surface. A display apparatus includes the backlight module and a display panel.
