摘要： The curing, by UV-light irradiation, of a sealing resin after injecting liquid crystal is made reliable. The display characteristics and the like of an in-plane electric field mode liquid crystal element are improved. To resolve these problems, the viscosity of the sealing resin is lowered, while bubbles mixed in the sealing resin are eliminated by ultrasonic waves, for example. Also, a means for eliminating ions and charges in the liquid crystal layer is devised.

摘要： The present invention is intended to eliminate any leakage of light which would occur, while in a black display state, due to a disordered alignment of liquid crystals around a pixel electrode in a liquid crystal device and to provide an improved contrast. The leakage of light around pixels can be suppressed and the contrast can be improved, for example, by rubbing the surface in a direction at an angle of 45 degrees with respect to any of the edges of a square pixel electrode 25 (a direction shown by the arrow 30) in a homeotropic type liquid crystal device.
