Abstract

The embodiment of the invention provides a method for preparing a display substrate and a display substrate. The preparation method comprises: providing a substrate and sequentially forming a resin layer arranged between the substrate and a hardened layer and a hardened layer on the substrate; arranging a baffle at one side, facing the hardened layer; arranging a plurality of hollow structures having different width in a first direction parallel to the baffle at the baffle; moving the baffle or the substrate bank and forth in the first direction; carrying out plasma etching on the hardened layer and the resin layer at one side, away from the substrate, of the substrate by using a plasma device to obtain a resin layer having a wedge-shaped structure; and depositing a light-reflecting layeron the resin layer to obtain a display substrate. Therefore, the reflective surface of the resin layer becomes smooth; the effective reflection surface is increased; and thus the utilization ratio oflight is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing a display substrate and the display substrate. Background technique [0002] Reflective liquid crystal display (R-LCD) is an LCD panel that uses external light reflection for display. Compared with a transmissive LCD device with a backlight, R-LCD has no backlight, reduces power consumption, and uses natural reflection display. Good for vision protection. The structure of R-LCD mainly includes: color filter substrate, liquid crystal layer, array substrate and reflective layer. [0003] At present, the reflective layer is only prepared by drying on the array substrate, but the resin material has fluidity during the drying process in this way, and it is difficult to obtain the desired shape. Contents of the invention [0004] The invention provides a method for preparing a display substrate to solve the problem that the existing method for preparing a re...
