摘要： An optical element comprises a light transmitting substrate (100), the light transmitting substrate comprises a first surface, and the first surface is provided with a plurality of strip-shaped prisms (200) which are arranged parallel to each other along a predetermined direction and extend along another predetermined direction. In the direction along which the plurality of strip-shaped prisms are arranged, a side of each strip-shaped prism close to a center of the light transmitting substrate has a refractive surface (201); from an end of the refracting surface close to the center of the light transmitting substrate to another end of the refracting surface close to an edge of the light transmitting substrate, the refracting surface inclines gradually along a direction away from the first surface. From the strip-shaped prism nearest to the center of the light transmitting substrate to the strip-shaped prism farthest to the center of the light transmitting substrate, an angle between the refracting surface and a normal of the first surface is gradually increased. A light guide plate (10), a prism (20), a backlight module and a display device are further provided.

摘要： The present disclosure provides a display baseplate and a display apparatus. The display baseplate includes a substrate, light emitter groups on the substrate, a light-adjusting structure on the substrate, and a diffusion structure on the substrate. The light emitter groups include light emitters. Chambers are disposed in the light-adjusting structure, and one light emitter group is located in one chamber; the orthographic projections of the chambers in which the light emitter groups are located on the substrate have basically same area; the light-adjusting structure is configured to converge light emitted by the light emitters to increase an amount of light of positive view angle of the display baseplate. The diffusion structure is at least partially located at a side of the light emitters away from the substrate, and configured to diffuse the light emitted by the light emitters.
