Problems solved by technology
At present, in LCD products, the photoresist material layer in the non-display area is usually set on a small color block. Defective display occurs at the edge of the display area
In response to this phenomenon, the usual solution is to increase the color blocks under the photoresist material layer in the non-display area, but for narrow-frame products with small space, the color blocks can only be placed in a specific limited area, so This solution cannot be realized in narrow bezel products

The invention provides a liquid crystal display panel as well as a preparation method and a liquid crystal display device thereof. A first metal layer, an insulating layer, a first passivation layer,a first color hinder layer, a second passivation layer and a photoresist layer are sequentially arranged between a first substrate and a second substrate, the first substrate comprises a display region and a non-display region surrounding the display region, and a thickness adjustment layer is also arranged in the non-display region and between the insulating layer and the first color hinder layer, so that a distance between the upper surface of the photoresist layer in the display region and the upper surface of the photoresist layer in the non-display region is in a preset range, film thickness of the non-display region can be increased without occupying a frame space of the substrate, difference between film thicknesses of the display region and the non-display region is avoided from being too great, and the phenomenon that display at the edge of the display region is poor is avoided; besides, the preparation method is simple, and display effect is good.
Description
[0001] 【Technical field】 [0002] The present application relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel, a preparation method thereof, and a liquid crystal display device. [0003] 【Background technique】 [0004] Liquid Crystal Display (LCD) has the advantages of light weight, thin thickness, low power consumption, easy to drive, and no harmful rays, and has been widely used in various information, communication, and consumer electronics products. [0005] A liquid crystal display generally includes a liquid crystal display panel, and the liquid crystal display panel includes an array substrate disposed opposite to each other, a color filter substrate, and a liquid crystal layer disposed between the array substrate and the color filter substrate. At present, in LCD products, the photoresist material layer in the non-display area is usually set on a small color block. Defective display occurs at the edge of the displa...
