Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, relate to a thin film transistor, an array substrate, a display panel and a display device. Background technique [0002] In the existing display device technologies, display panels are mainly divided into two mainstream technologies: liquid crystal display panels and organic light-emitting display panels. Among them, the liquid crystal display panel forms an electric field capable of controlling the deflection of liquid crystal molecules by applying a voltage on the pixel electrode and the common electrode, and then controls the transmission of light to realize the display function of the liquid crystal display panel; the organic self-luminous display panel uses organic electroluminescent materials , when a current passes through the organic electroluminescent material, the luminescent material will emit light, thereby realizing the display function of t...
