Title: Liquid crystal display device
Inventor: OKADA MASAKO
IPC: G02F1/137
Filed: 1991-09-30
Abstract: PURPOSE:To improve working efficiency by adding a silicone oil to a liquid crystal material at a slight ratio at the time of injecting a liquid crystal material to a liquid crystal panel, by which bubbling is substantially prevented even under a reduced pressure and the time for defoaming is shortened. CONSTITUTION:The compd. expressed by formula I is incorporated at >=0.03wt.% and <=1.5wt.% into the liquid crystal of the liquid crystal display device constituted by forming respective transparent electrodes 2a, 2b on the opposite surfaces of a pair of light transparent substrates 1a, 1b, forming insulating films 3a, 3b covering the respective transparent electrodes 2a, 2b, forming oriented films 4a, 4b covering these films, and packing the liquid crystal between a pair of the light transparent substrates 1a and 1b. In the formula I, X and Y denote a hydrogen atom or 1 to 10C alkyl group; n denotes 0 to 8 integer. There is no need for a heating treatment of the liquid crystal material in such a case and a colorless transparent defoaming agent having excellent chemical stability is mixed with the liquid crystal. Since the ratio of mixing this agent is slight, the degradation in the voltage holding characteristic of the liquid crystal material is obviated and the excellent reliability is obtd.
