Array substrate and display panel

Abstract

The invention discloses an array substrate and a display panel. A base of the array substrate comprises a plane area and a step area; the step area comprises a bending area and a binding area; a firstalignment mark and a second alignment mark are arranged on the surface of the substrate. The second alignment mark is arranged in the binding area. The first alignment mark is arranged in the plane area. The first alignment mark and any structural layer in the pixel structure are arranged on the same layer or the first alignment mark is located between the pixel structure and the substrate, so that the problem that the first alignment mark must be arranged in the bending area due to the absence of the arrangement position of the first alignment mark when all or most areas of the plane area are used for arranging the pixel structure is solved; thus, the problem that after the bending area is bent towards the side away from the display direction, the longitudinal distance between the firstalignment mark arranged in the bending area and the second alignment mark arranged in the step area is too large, and consequently a camera device cannot accurately grab the relative position relationbetween the first alignment mark and the second alignment mark is solved.

Description

technical field [0001] The present application relates to the field of display technology, and more specifically, to an array substrate and a display panel. Background technique [0002] With the continuous development of display technologies, the screen-to-body ratio of display devices continues to increase, and is constantly developing towards a true full screen. [0003] The emergence of flexible substrates provides a new solution for further increasing the screen-to-body ratio of display devices. Refer to figure 1 , figure 1 It is a schematic cross-sectional structure diagram of a flexible substrate 10 of a display device. In the display device, the flexible substrate 10 includes a planar region 11 and a step region 12 adjacent to the planar region 11. An array arrangement is arranged in the planar region 11. display pixels, the step area 12 is used to bind the chip or to set the wiring. After the chip or the wiring is set in the step area 12 of the flexible substrate ...
