Abstract
The embodiment of the invention provides a TFT substrate, a liquid crystal display panel and a display device. The TFT substrate comprises a substrate, a grid electrode, a grid electrode insulating layer, an active layer and a source and drain electrode layer. Wherein the grid electrode insulating layer comprises a first insulating layer which is in direct contact with the grid electrode, and the first insulating layer is made of an insulating material with the electron affinity lower than 3eV. According to the TFT substrate provided by the embodiment of the invention, the material of the first insulating layer in direct contact with the grid electrode in the grid electrode insulating layer is the insulating material of which the electron affinity is lower than 3eV, so that electrons on the grid electrode can be effectively prevented from transitioning to the grid electrode insulating layer to cause performance degradation of a TFT device, and the stability of the TFT device in a high-brightness environment is improved; the liquid crystal display panel comprising the TFT substrate can work under high-brightness backlight, display anomalies such as greenness and yellowing are avoided, and when the liquid crystal display panel is applied to a high-brightness outdoor display product, the display quality of the outdoor display product can be improved.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a TFT substrate, a liquid crystal display panel and a 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] A liquid crystal display device generally includes a housing, a liquid crystal display panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal display panel is mainly composed of an array substrate (ThinFilmTransistor Array Substrate, TFT Array Substrate), a color filter substrate (ColorFilter Substrate, CF Substrate), and a liquid crystal la...
