Display panel, preparation method thereof and display device

Abstract

The invention relates to the technical field of display, and discloses a display panel and a preparation method thereof and a display device. The display panel comprises a first substrate, a second substrate and at least one spacer, wherein the first substrate and the second substrate are arranged in a combined manner, the spacers are positioned between the first and second substrates, the second substrate is provided with an alignment layer facing to the first substrate, the alignment layer is provided with recesses corresponding to all the spacers, and each spacer is fixed on the first substrate and butted in the corresponding recess. Since the alignment layer is provided with the recesses corresponding to the spaces and each spacer is butted in the corresponding recess, even the display panel generates alignment layer chips or spacer chips due to external force, the chips are retained in the recesses, and probability of diffusing to a display region is lowered; therefore, fine bright spots on the display panel are decreased, and further image quality of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Among the flat panel display devices, Thin Film Transistor Liquid Crystal Display (TFT-LCD) has the characteristics of small size, low power consumption, relatively low manufacturing cost and low radiation, and occupies a dominant position in the current flat panel display market. leading position. [0003] Traditional LCD products such as figure 1 as shown, figure 1 It is a structural schematic diagram of a liquid crystal display panel in the prior art, figure 1 A pixel unit of a display panel is used as an illustration in the above, the liquid crystal display panel includes a first substrate 1 and a second substrate 2 placed opposite to each other, and a spacer 4 between the first substrate 1 and the second substrate 2, wherein , the first substrate 1 is a color fil...

AI Technical Summary

Problems solved by technology

After the product is boxed, various processes such as thinning, polishing, and coating will be carried out to generate stress on the panel, and the spacer 4 will repeatedly rub against the alignment layer on the second substrate 2 under the action of stress. Orientation layer debris or spacer debris, these debris may move to the display area, causing small but large number of bright spots to appear on the display screen of the product, generally called fine bright spots (Zara Particle), which seriously affects Display panel picture quality

[0004] The defect of the prior art is that fine and dense bright spots appear in the display panel, resulting in poor picture quality of the display panel
