Array substrate, display panel and display device

Abstract

The present application discloses an array substrate, a display panel and a display device, and relates to the technical field of display. The array substrate includes a display area, a non-display area, a binding area, a fanout trace area and alignment film blocking structures, wherein the non-display area is disposed around the display area, the binding area is arranged in the non-display area and includes a plurality of conductive pads, the fanout trace area is arranged between the display area and the binding area and includes a plurality of first fanout traces, second fanout traces and third fanout traces, the first fanout traces and the second fanout traces extend in a first direction and are arranged in a second direction, the first fanout traces, the second fanout traces and the third fanout traces are located in different film layers, signal leads in the display area are electrically connected with the conductive pads via the fanout traces, the alignment film blocking structures are disposed in the fanout trace area and are arranged in the same layer as the third fanout traces, and in the second direction, vertical projections of adjacent two alignment film blocking structures toward the first direction are continuous. In this way, the diffusion of an alignment film to the binding area can be effectively blocked.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to an array substrate, a display panel and a display device. Background technique [0002] A liquid crystal display is a commonly used flat panel display at present, and a thin film transistor liquid crystal display (ThinFilm Transisitor Liquid Crystal Display, TFT-LCD for short) is a mainstream product in the liquid crystal display. The liquid crystal display panel is an important part of a liquid crystal display, mainly including an array substrate and a color filter substrate arranged opposite to each other, and a liquid crystal layer is filled between them. As panel displays are more and more widely used, widescreen technology has become an important technical item. At the same time, the technology of narrow lower borders of display panels has also attracted more and more attention. Advanced electronic products, especially portable electronic products, tend to be sm...

Problems solved by technology

However, in the process of forming the alignment film, due to the low viscosity of the PI liquid, it is not easy to control, so the PI liquid is easy to diffuse to the binding area, thereby affecting the binding effect of the array substrate, and may also cause the PI liquid in the display area to be too large. Thin, resulting in uneven display of the display panel
