Display panel, manufacturing method thereof and display device

Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device. The display panel comprises a first substrate, a second substrate, a chip-on-film and a light shading array layer, wherein one end of the first substrate exceeds the second substrate to form a binding end; the chip-on-film is bound on the inner side of the binding end; a metal signal wire which is positioned in a non-pixel region is arranged on the inner surface of the first substrate; and the light shading array layer is positioned in the non-pixel region and completely shades the metal signal wire.Because the first substrate faces a looker and the chip-on-film is bound on the inner side of the binding end of the first substrate, frameless design is realized; the patterning light shading array layer is arranged on the outer surface of the first substrate, a pattern which corresponds to the metal signal wire on the inner surface of the first substrate is formed by the light shading array layer to cover the metal signal wire, when entering the display panel, external environment light can be weakened or obstructed in the light shading array layer, the light intensity which can reach the metal signal wire is greatly weakened, and therefore, the reflection degree of the metal signal wire is reduced.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the rapid development of LCD (Liquid Crystal Display) panels, LCD displays have gradually become the mainstream of display technology due to their ultra-thin, light weight, non-radiation, and stable performance. [0003] Borderless displays are not necessarily frameless. The liquid crystal panel of the display usually includes a color film (CF) substrate and an array (TFT Array, or thin film transistor array) substrate. Liquid crystal is filled between the two. In the traditional In the overall design of the borderless display, the color filter substrate side faces outward and the array substrate side faces the backlight source, that is, the color filter substrate of the liquid crystal panel is seen by the naked eye when the final user looks at it. [0004] Th...

AI Technical Summary

Problems solved by technology

[0004] The LCD panel is placed on the back panel. Due to the presence of the Bonding area of ​​the array substrate, the size of the array substrate of the LCD panel will be larger than the size of the color filter substrate. The Bonding area of ​​the array substrate protrudes toward the side, and the frame needs to be designed to Therefore, the traditional LCD panel needs to use complex optical components to cover the border of the non-display area, and it is difficult to achieve a true borderless design.
