摘要： The present disclosure provides a positive photoresist composition including a major adhesive material and a photosensitizer, wherein the photoresist composition further includes a photoisomerizable compound which would be converted into an ionic structure with an increased degree of molecular polarity after ultraviolet irradiation. The formation of the ionic structure with increased polarity of the molecule reduces the adhesion between the positive photoresist and the organic film layer, facilitates stripping after formation of the via, and improves the product rate of pass. Further, the present disclosure provides a via-forming method using the positive resist composition, a display substrate including the via formed by the via-forming method, and a display device including the display substrate.

摘要： The present disclosure provides a method for manufacturing a display panel, a display panel and a to-be-cut display panel, and relates to the field of display technologies. The method includes: forming a first electrostatic protective circuit and a source and drain conductive pattern on a base substrate; removing the source and drain conductive pattern within the target cutting region; forming a to-be-cut display panel by forming a superstructure on the base substrate; and cutting the to-be-cut display panel in the target cutting region. When manufacturing the internal structure of the display panel, only the source and drain conductive pattern in the target cutting region is removed, while the electrostatic protective circuit in the target cutting region is retained. In this way, the electrostatic protective circuit can always play the function of electrostatic protective during the formation of the internal structure of the display panel, such that the internal structure of the display panel is avoided from being damaged by electrostatic, the manufacturing yield of the display panel improved, the problem of low manufacturing yield of the display panel in the related technology is solved, and the effect of improving the manufacturing yield of the display panel is achieved.
