Title:
LIQUID CRYSTAL SEALING AGENT AND LIQUID CRYSTAL DISPLAY CELL USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/010731
Kind Code:
A1
Abstract:
Provided is a liquid crystal sealing agent for use in a liquid crystal dropping process which, due to the particularly excellent adherence to an organic film such as an oriented film, does not readily peel from upper/lower substrates even in various environments, and further, has excellent fundamental characteristics as a liquid crystal sealing agent, such as low liquid crystal staining properties and heat resistance. This liquid crystal sealing agent is characterized in that, when the strength of adhesive bonding to an ITO substrate at 25ºC after curing for 1 hour under an atmosphere of 120ºC, following irradiation of 3000 mJ/cm2 ultraviolet rays, is taken as A [MPa], the strength of adhesive bonding at 120ºC after said curing is taken as B [MPa], and the strength of adhesive bonding to an ITO substrate at 25ºC after curing with only 3000 mJ/cm2 ultraviolet rays is taken as C [MPa], A, B and C satisfied the relational expressions shown by expressions (1) and (2) below. B ≥ 0.5 × A (1) C ≥ 0.3 × A (2)
