Problems solved by technology
However, it is difficult to replace the metal electrodes of the array substrate with high-resistivity transparent electrodes, and the light-shielding matrix absorption on the side of the color filter substrate is the key link to prevent color crosstalk and improve large viewing angle deviation, so another method is needed

The invention provides a color film substrate and a liquid crystal display. The color film substrate includes a substrate, a light shielding matrix and a plurality of color blocking units, wherein the light shielding matrix and the color blocking units are disposed above the substrate along a direction parallel to the substrate; the projections of the light shielding matrix and a plurality of the color blocking units on the substrate are connected but not intersected; the light shielding matrix includes a plurality of light reflection units and a plurality of light absorption units; a plurality of the light reflection units are used for reflecting light and disposed above the substrate; a plurality of the light adsorption units are used for absorbing light and arranged on the light reflection units. According to the scheme, the light shielding matrix is designed in a structure of reflecting light at one surface and absorbing light at the other surface; when the light emitted by a backlight module passes through the light shielding matrix, part of the light can be reflected back into the backlight system, so that the light can be recycled, the backlight loss is reduced and the utilization rate of backlight resources is improved.
Description
technical field [0001] The invention relates to the field of manufacturing liquid crystal display panels, in particular to a color filter substrate and a liquid crystal display. Background technique [0002] In the contemporary information society, the importance of the display as a visual information transmission medium is further strengthened. In order to occupy a dominant position in the future, the display is moving towards lighter, thinner, lower power consumption, lower cost and better image quality. trend development. [0003] The core of display technology is to reproduce the perception of the real world by the human eye. The current mainstream display technologies include LCD (Liquid Crystal Display) and OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode). , contrast, bright and dark state control, and reliability have different advantages. Among them, LCD display technology has a long history of development, and has the advantages of mature technolo...
