Display panel, manufacturing method thereof, and display device

Abstract

The present invention relates to a display panel having a display region and a non-display region, comprising: a first substrate and a second substrate oppositely provided and a layer of liquid crystal molecule located between the first substrate and the second substrate, wherein the first substrate and the second substrate each are provided with an alignment film at a position corresponding to the display region, and each are provided with a sealant region for applying sealant at a position corresponding to the non-display region, wherein: the sealant region on a surface of the first substrate facing the liquid crystal molecule layer is provided with a first raised layer by which the sealant region of the first substrate is higher than the display region thereof; and the sealant region on a surface of the second substrate facing the liquid crystal molecule layer is provided with a second raised layer by which the sealant region of the second substrate is higher than the display region thereof. The above display panel has improved display quality and has a narrow border at the same time.

Description

technical field [0001] The invention relates to the technical field of displays, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] In the preparation process of the liquid crystal display device, it is difficult to obtain the desired alignment state of the liquid crystal material molecules only by injecting the liquid crystal material between the glass substrates. Therefore, it is necessary to display the color filter substrate and the array substrate in the liquid crystal display device An alignment film is formed in the area to set the pre-tilt angle of the liquid crystal molecules, so that the liquid crystal molecules are arranged neatly. [0003] The formation of the alignment film usually uses a photosensitive plate to transfer the photoalignment liquid to the color filter substrate and the array substrate, and then performs traditional rubbing or light alignment. When using a photosensitive plate to t...

Problems solved by technology

[0004] However, the non-display area of ​​the narrow-frame display device in the prior art is relatively small. When the color filter substrate 01 and the array substrate 02 are connected in pairs to form a display panel, the coated area 03 of the sealant is easy to contact with the alignment film 04. The edges partially overlap, as in figure 1 As shown, or the edge of the alignment film 04 protrudes from the coating area 03 of the sealant, such as figure 2 shown

The alignment film includes an upper alignment layer for alignment and a bottom layer with high mechanical strength, while the upper alignment layer of the alignment film has low mechanical strength and is easy to peel off from the frame sealant, making it easy for moisture in the external environment to enter the display panel, resulting in defective display panels show
