Problems solved by technology

[0005] However, in the region where the frame is narrower, the overlapping of the encapsulant 30 and the first alignment layer 11 and the second alignment layer 21 will cause the cell thickness of the display panel 01 to be higher than that of the region where the frame is wider. There will be a cell thickness difference (marked as Δd in the figure) at the border, that is, the display panel 01 will produce a phenomenon of uneven cell thickness, which will cause the liquid crystal molecules filled between the color filter substrate 10 and the array substrate 20 to be pulled and deformed, making the display panel The uneven display of the surrounding images (that is, the Mura phenomenon), resulting in poor display of the display panel, limits the further development of the narrow bezel display panel

Abstract

The embodiment of the invention provides a display panel and a preparation method thereof, and a display device, and relates to the technical field of displaying. Non-uniformity of the box thickness can be improved; the phenomenon of Mura at the peripheral edge of a displayed picture can be reduced; the quality of the picture is improved. The display panel comprises a color film base plate and an array base plate which are oppositely arranged, and encapsulation glue positioned between the color film base plate and the array base plate, wherein the color film base plate comprises a protection layer and a first alignment layer which are far away from a first substrate base plate in sequence; the array base plate comprises a passivation layer and a second alignment layer which are far away from a second substrate base plate in sequence; the encapsulation glue is positioned in an encapsulation region of the display panel; the encapsulation region comprises a first sub region and a second sub region; in the first sub region, the encapsulation glue is overlapped with the first alignment layer and the second alignment; a first groove is formed in the protection layer, and the upper part of the encapsulation glue is positioned in the first groove, and / or a second groove is formed in the passivation layer, and the lower part of the encapsulation glue is positioned in the second groove; in the second sub region, the encapsulation glue is not overlapped with the first alignment layer and the second alignment.

Description

technical field [0001] The 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] At present, since the narrow frame display panel can provide viewers with a more comfortable viewing effect and can effectively increase the display area, it has become the latest concept in the industrial design of the display panel. [0003] like figure 1 As shown, the display panel 01 is usually composed of a color filter substrate and an array substrate that are boxed together. In the prior art, since the substrates of the color filter substrate and the array substrate are usually glass materials, the vertical frame of the display panel needs to be formed. To stabilize the glass substrate, it is difficult to achieve a narrower width for the vertical frame of the display panel. [0004] Based on this, if figure 2 As shown, in order to meet the requirements of the current n...
