Array substrate and liquid crystal display device

Abstract

The application provides an array substrate and a liquid crystal display device. The array substrate includes a substrate and a first light-transmitting layer. The substrate has a first surface and a second surface opposite to the first surface. The first surface is located on the light incident side of the array substrate. At least one first light-transmitting layer is disposed on the first surface of the substrate, the refractive index of the at least one first light-transmitting layer is greater than that of air, and the refractive index of the at least one first light-transmitting layer and the refractive index of the substrate are along the first The light-transmitting layer increases in the direction of the substrate, and the thickness of each first light-transmitting layer satisfies a specific functional relationship with each color light in at least one color light, and the at least one color light is selected from one of blue light, red light and green light. One or two kinds, each color light corresponds to at least one first light-transmitting layer. The deviation of the chromaticity coordinates corresponding to the light emitted by the liquid crystal display device is improved, and the transmittance of the light emitted by the liquid crystal display device is increased.

Description

technical field [0001] The present application relates to the field of display technology, and in particular, to an array substrate and a liquid crystal display device. Background technique [0002] With the advancement of technology, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has gradually replaced the traditional cathode ray tube display device due to its superior characteristics such as thin body, low power consumption and no radiation. TFT-LCD mainly includes a thin film transistor substrate (Array Substrate), a color filter (Color Filter, CF) substrate and a liquid crystal layer sandwiched between the thin film transistor substrate and the color filter substrate, the thin film transistor substrate, the color filter substrate and the color filter substrate. The liquid crystal layer may form a plurality of pixels arranged in an array. [0003] In recent years, in the design of TFT-LCD, the high definition of TFT-LCD display and the improvement of color reprodu...

Problems solved by technology

For example, for TFT-LCD, the light emitted by it can correspond to the CIE 1931 chromaticity coordinates, and in terms of chromaticity coordinates, the three primary colors (blue, green and red) all have their corresponding color points, that is, the chromaticity triangle If the three primary color points deviate too much from the coordinates, it means that the color of the TFT-LCD display screen is distorted, resulting in poor screen display, and poor screen display will reduce the user's viewing experience.

[0004] Therefore, it is necessary to propose a technical solution to solve the problem that the light emitted by the TFT-LCD deviates from the chromaticity coordinates and the color distortion occurs when the TFT-LCD displays the picture
