Abstract: This invention relates to a photoresist stripper composition. The photoresist stripper composition according to the present invention comprises at least one choline compound; at least one polar aprotic solvent; and water; the weight percentage of the choline compound is from 2.5 to 50%, preferably from 5 to 50%, more preferably from 7 to 30%, and most preferably from 9 to 18% by weight based on the total weight of the composition. The photoresist stripper composition according to the present invention exhibits excellent photoresist cleaning performance and low etching to the substrate.

Abstract: The present invention relates to an improved one-drop-filling process of producing a liquid crystal display having a liquid crystal layer between a first substrate and a second substrate, comprising steps of applying a thermally curable resin composition on a sealing region at a periphery of a surface of the first substrate; conducting a first thermal curing of the thermally curable resin composition at a temperature of 40° C. to 75° C., and obtaining a partially cured product; dropping liquid crystal on a central area encircled by the sealing region of the surface of the first substrate or the corresponding area of the second substrate, and forming the liquid crystal layer; overlaying the second substrate on the first substrate; and conducting a second thermal curing of the partially cured product.

Abstract: The present invention relates to a curable resin composition for sealing liquid crystal. The curable resin composition comprises a maleimide resin, an epoxy resin, a thermal free radical initiator, and a latent epoxy curing agent. More specifically, the resin composition can be cured with a combination of ultraviolet (UV) radiation and heat, resulting in a cured product with good curability in light-shielded area, excellent adhesion strength and high reliability.
