Abstract

The invention provides a display substrate, a display device and a method for manufacturing the display substrate, and belongs to the technical field of display. The display substrate can at least partially solve the problem of the low photoelectric conversion efficiency when a photoelectric conversion layer is integrated in an existing liquid crystal display panel. The display substrate comprisesa base and a pixel light-emitting region and a non-light-emitting region divided on the base, the photoelectric conversion layer is disposed on one side of the base, the orthographic projection of the photoelectric conversion layer on the base is located in the non-light-emitting region, one side, away from the base, of the photoelectric conversion layer is provided with a polarizing structure, and a side, away from the polarizing structure, of the base is a display surface.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a display substrate, a display device, and a manufacturing method of a display substrate. Background technique [0002] In the prior art, there is a solution of integrating the photoelectric conversion layer into the color filter substrate of the liquid crystal display panel. That is, the photoelectric conversion layer is integrated on the side of the color filter substrate facing the liquid crystal layer, and a polarizer is attached on the side of the color filter substrate facing away from the liquid crystal layer. The liquid crystal display panel thus constituted can not only realize liquid crystal display, but also use ambient light such as sunlight or lights in a natural environment to generate power, thereby achieving the purpose of reducing power consumption. In order not to affect the display, the photoelectric conversion layer is usually arranged in the are...
