Title:
SEALING AGENT FOR ONE-DROP FILL METHOD, MANUFACTURING METHOD FOR LIQUID CRYSTAL DISPLAY PANEL, AND LIQUID CRYSTAL DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/200220
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a sealing agent for the one-drop fill method with which a sealing member having good adhesion strength with a substrate can be formed even when exposed to a high-temperature, high-humidity environment; a liquid crystal display panel using the same; and a manufacturing method therefor. The sealing agent for the one-drop fill method with which this problem is to be solved is used in the one-drop fill method. When a film is formed by configuring the sealing agent for the one-drop fill method into a film having a thickness of 1,000 μm, illuminating the same with 3,000 mJ/cm2 of light, and heating the same at 120°C for one hour, the initial Young's modulus of the film at 120°C is no more than 1.0x108 Pa as measured by a dynamic viscoelasticity measurement device, and the difference between the initial Young's modulus and the post-PCT Young's modulus of the film at 120°C is no more than 8.0x107 Pa as measured by the dynamic viscoelasticity measurement device after the film has been stored in a 121°C, 100% Rh environment for 24 hours.
