Problems solved by technology

[0005] The present invention provides a display panel, an array substrate, and a display device to solve the problem of using a color-resist stack formed by overlapping color layers to replace a black matrix in the existing liquid crystal display technology to form a light-shielding area in the frontal edge area. The layer itself is a light-transmitting material, and a small amount of light will still pass through the color-resist laminate with overlapping color layers, which will affect the shading effect

Abstract

The invention provides a display panel, an array substrate and a display device. The array substrate of the display panel includes multiple thin film transistors arranged on a first substrate, multiple first metal layers arranged at intervals on the outer edge of a display area of the first substrate, insulated layers covering the first metal layers and second metal layers disposed on the insulated layers at intervals, wherein the projections, on the first substrate, of the second metal layers completely cover the interval between every two adjacent first metal layers, correspondingly lightproof light shielding layers are formed in the light emitting directions of the first and second metal layers, a lightproof light shielding layer is thus formed on the outer edge of the display area of the first substrate, and a frontal border light shielding effect can be achieved. Original black matrices are replaced, the manufacturing cost and the manufacturing process are reduced, and the metal layers cannot be permeated by light, so that the formed light shielding layers have a better light shielding effect, a light leakage phenomenon is avoided, and the purpose of saving the cost when it isensured that the frontal border is completely lightproof is achieved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, an array substrate and a display device. Background technique [0002] Liquid crystal display panel has many advantages such as thin body, power saving, no radiation, etc., has been widely used, and occupies a dominant position in the field of flat panel display. A liquid crystal display panel generally includes an array substrate, a color filter substrate, and a liquid crystal layer sandwiched between the array substrate and the color filter substrate. For traditional vertical alignment (Vertical Alignment, VA) liquid crystal display panels, thin film transistors (Thin Film Transistor, TFT) arranged in a matrix are usually arranged on the array substrate, and filters are usually arranged on the color filter substrate (CF substrate). The color resist layer for light, the black matrix (Black Matrix, BM) used for shading to form a frame-shaped frontal edg...
