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 thin film transistor, including a base substrate, an active layer and a source/drain, and a conductive layer. The active layer and an outer edge of the conductive layer are formed in the same etching process. The present disclosure further provides a method for manufacturing a thin film transistor, including forming an active material layer and a conductive material layer, forming a photoresist on the conductive material layer, exposing and developing the photoresist by means of a halftone mask, removing segments of the active material layer and the conductive material layer corresponding to a photoresist completely-removed region by a same etching process, partially removing the photoresist in a photoresist completely-retained region and completely removing the photoresist in a photoresist partially-retained region, and removing a segment of the conductive material layer corresponding to the photoresist partially-retained region.
