Abstract

The present invention relates to the technical field of display devices, and discloses an array substrate, a display panel and a display device. The array substrate includes: a base substrate; a patterned thin film transistor layer and a first passivation layer sequentially arranged on the base substrate , a quantum dot layer, a color filter layer, a flat layer and a metal wire grid polarizing layer, wherein the orthographic projection of the quantum dot layer on the substrate is located within the orthographic projection of the color filter layer on the substrate. In the array substrate, both the quantum dot layer and the metal wire grid polarizing layer are arranged on the base substrate, and the thermal influence on the quantum dot layer in the manufacturing process is blocked by the color filter layer, and the backlight is improved by wavelength conversion. Utilization, thus meeting the display requirements.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to an array substrate, a display panel and a display device. Background technique [0002] With the development of liquid crystal display products, the transmittance and color gamut of liquid crystal panels have been limited by bottlenecks, and wavelength conversion has to be used to improve the utilization rate of backlight to meet display requirements. [0003] The quantum dot material is an excellent wavelength conversion material. The quantum dot material is made into a photoresist to form a quantum dot film layer with a pixel-level pattern, which can specifically convert the backlight into the color required by the pixel, and greatly improve the backlight utilization. Rate. However, due to the fluorescent properties of quantum dot materials, it will completely destroy the polarization state of light, so it must be used with a built-in polarizer. At present, th...
