Title: Active matrix type liquid crystal display device
Inventor: TOMIOKA YASUSHI
IPC: G02F1/136
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To reduce unevenness in display due to an image persistence and after-image phenomenon and to enhance image quality by making the glass transition temp. of the surface of an alignment controlling layer not less than the nematic-isotropic phase transition temp. of a liquid crystal compsn. forming a liquid crystal layer. SOLUTION: In a horizontal electric field system, the seizure of an image and after-image correspond to difficulty in the restitution of distortion of liquid crystal molecules in the intrasurface direction of a substrate. The formation of a high elasticity polymer surface hardly affected by rotational torque due to the driving of liquid crystal molecules is effective to suppress the occurrence of after-image phenomenon. Indices for the selection of a high elastic modulus alignment layer include the glass transition temp. Tg of the polymer of the orienting film besides the elastic modulus. When the glass transition temp. Tg of the surface of the alignment layer or a part near the interface between the layer and a liquid crystal layer is made higher than the nematic-isotropic phase transition temp. T(N-I) of the liquid crystal, the surface of the alignment layer exists in a very hard state close to the state of glass and becomes less liable to elastic deformation by rotational torque and the occurrence of after-image is minimized.
