Abstract: The present application provides a display substrate, a display panel, and a display device. The display substrate includes a substrate layer. The substrate layer includes a first substrate portion and a second substrate portion joined to each other. The first substrate portion is made of a first substrate material and configured to be disposed opposite to a photosensitive element. The second substrate portion is made of a second substrate material. A light transmittance of the first substrate material is larger than or equal to a light transmittance threshold, and a light transmittance of the second substrate material is smaller than the light transmittance threshold.

Abstract: The present invention provides a method for detecting a size of a pattern made by photolithography, which being applied for detecting a size of a pattern formed on an array substrate of a liquid crystal display including: deriving function layer parameters and position parameters of a detection-pattern; deriving a thickness-profile of the detection-pattern according to the function layer parameters and the position parameters of the detection-pattern; deriving a plane-profile of the detection-pattern according to the thickness-profile of the detection-pattern; proceeding a size-detection to the plane-profile of the detection-pattern.
