Title:
DISPLAY PANEL, DISPLAY APPARATUS AND MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/000846
Kind Code:
A1
Abstract:
Disclosed are a display panel, a display apparatus and a manufacturing method, which are used to solve the problem that in the process of performing quality evaluation on a liquid crystal panel, the volume of a liquid crystal (103) in a liquid crystal panel cell changes as the nature of thermal expansion and cold shrinkage of the liquid crystal (103), such that bubble defects or water ripple defects occur on the liquid crystal panel. The display panel comprises: an array substrate (101) and an opposite substrate (102) arranged opposite each other, a liquid crystal (103) and a compensation structure (104) which is in direct contact with the liquid crystal (103) and has the nature of cold expansion and thermal shrinkage, wherein the compensation structure (104) is used to compensate for a change in the volume of the liquid crystal (103) after expansion or shrinkage, so as to keep the cell thickness of the display panel unchanged. The compensation structure (104) with the nature of cold expansion and thermal shrinkage is arranged in the liquid crystal (103) of the display panel. Since the nature of cold expansion and thermal shrinkage of the compensation structure (104) is opposite to the nature of thermal expansion and cold shrinkage of the liquid crystal (103), a change in the volume of the liquid crystal (103) under the condition of a high/low temperature test can be effectively compensated by adjusting the dosage of the compensation structure (104), thereby preventing the occurrence of various defects of the display panel in the high/low temperature test.
