Abstract: A display panel and a display device are disclosed. In preparing the display panel, based on a height difference formed between a plurality of first column spacers and a plurality of second column spacers, as a color filter substrate deforms during a vacuum assembly process, a deformation area of a blind hole area increases because the second column spacers are not in contact with an array substrate in the blind hole area, resulting in a decrease in a radius of curvature of the deformation of the blind hole area, so that an amount of deformation is reduced and poor focusing due to Newton's ring effect on the blind hole can be prevented.

Abstract: The present disclosure provides a cover, a display device, and a method for manufacturing the display device. By forming a first via hole in an electronic component disposing region when an optically clear adhesive is formed on the cover, via holes are formed because the optically clear adhesive cannot form in the electronic component disposing region. Thus, the optically clear adhesive does not have portions having different thicknesses, thereby preventing bubbles from forming in a blind hole region, and solving technical problems of the existing display device that the OCA has bubbles around the corresponding blind hole region, which affects photographing quality.

Abstract: The present disclosure provides a polarizer protective film and a method for tearing off the same. The polarizer protective film is used for adhering to a surface of a polarizer. The polarizer protective film is provided with an extending portion protruding from the polarizer. In the polarizer protective film of the present disclosure and the method for tearing off the same, an extending portion is provided on the polarizer protective film, so that when the polarizer protective film is torn off, there is a good force bearing point to achieve the effect of tearing off the polarizer protective film at one time.

Abstract: The present invention provides a display module and a full lamination method. The display module includes a cover plate, a glass substrate, a display panel, and an adhesive layer. The adhesive layer includes a main part and an extension part. The adhesive layer is extended beyond the glass substrate, and UV irradiation is performed on a lateral side of the display module to solidify the extension part, so that impurities such as ambient water/moisture are prevented from entering the inside of the display module. Two deaerating treatments are performed to effectively avoid occurrence of bubbles at a boundary between a visible region and a black matrix region.
