  • Patent number: 11061277
    Abstract: A diffusion sheet, a backlight module, a liquid crystal display panel and a display device are disclosed. The diffusion sheet comprises a base layer, a white printed layer and a black printed layer. The base layer comprises a peripheral region and a light transmitting region. The white printed layer and the black printed layer are arranged in the peripheral region. In a direction from a light incident surface to a light exit surface of the base layer, the black printed layer and the white printed layer are arranged in this order. An orthographic projection of the black printed layer on the base layer falls within an orthographic projection of the white printed layer on the base layer. In this way, the white printed layer can block a shadow which is formed by reflection of the black printed layer from the prismatic sheet, and thus improve the display quality.
