Problems solved by technology
when figure 1 When the shown liquid crystal display device displays a black screen, the liquid crystal layer 300 has almost no influence on the polarization state of normal incident light. The optical axis directions of the liquid crystal molecules in the layer 300 are not parallel. After passing through the liquid crystal layer 300, the liquid crystal layer 300 has an optical path difference (Retardation) relative to the obliquely incident light, thereby generating light leaking from the upper polarizer, resulting in light leakage , especially when quantum dot materials are used to make color-resist blocks, since the light-emitting direction of quantum dots is in all directions, the above-mentioned light leakage problem will also cause the light emitted by adjacent sub-pixels to alias, thereby affecting the display image quality clarity and color accuracy

Abstract
The invention provides a liquid crystal display device. A black matrix can shield black screen light leakage of the liquid crystal display device by increasing the height of the black matrix, the height of the black matrix is increased in the direction of emergent light of quantum dot color resistance blocks when the quantum dot color resistance blocks are adopted, light mixing of the quantum dot color resistance blocks between connected pixels is prevented, applicability to a COA (color-filter on array)-type liquid crystal display device can be realized, light leakage is further reduced with a COA technology, and the display effect of the liquid crystal display device is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display device. Background technique [0002] With the development of display technology, liquid crystal displays (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal Various consumer electronic products such as digital assistants, digital cameras, notebook computers, and desktop computers have become the mainstream of display devices. [0003] Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by elect...
