摘要： 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.

摘要： A light guide plate includes a body region and a light incident region. The body region has a light exiting surface, an opposite base surface, and a side surface between the light exiting surface and the base surface. The light incident region is located at the side surface of the body region for receiving incident light and includes projections protruding outwards from the side surface of the body region, and a cavity is defined between adjacent projections. Each projection has a top surface and outer side walls. The outer side walls also define inner side walls of each cavity together with a bottom surface. The top surface, side walls, and bottom surface together are a light incident surface of the light incident region. An angle between the top surface and each outer side wall is called an apex angle, which is greater than 90 degrees.

摘要： Provided are an array substrate, a display panel and a display device. The array substrate includes a display region and a peripheral region. The peripheral region includes a chip-on-film bonding region, and the peripheral region has a recessed structure configured to fill a bonding material. The recessed structure is between the chip-on-film bonding region and a lateral side of the array substrate. The chip-on-film bonding region is between the display region and the lateral side. By disposing a recessed structure configured to fill the bonding material in the peripheral region, a gap is difficult to occur between the chip-on-film in the chip-on-film bonding region and the array substrate, preventing entry of water vapor to cause corrosion of lead wires and short circuits of lead wires. The defect ratio of the array substrate, the display panel, and the display device is reduced, and the product quality is improved.
