Title: Liquid crystal display device
Inventor: MIYAZAKI DAISUKE
IPC: G02F1/1339
Filed: 1996-09-05
Granted: 2001-06-16
Abstract: A liquid crystal display element includes a pillar-shaped spacer as a stack of a plurality of color layers, which exists on either an active matrix substrate or an opposite substrate facing to the former substrate. An impurity concentration and an impurity elution quantity of the color layer closest to a switching element among the color layers constituting the pillar-shaped spacer are made lowest among the plurality of color layers, or a bridging density of a resin is made highest among the color layers, thereby restraining an influence of the impurities upon the switching element and enhancing a display quality and a yield. Damages to contact areas when the active matrix substrate is disposed facing to the opposite substrate are reduced by making a hardness of the farthest layer from a surface of a substrate on which the pillar-shaped spacer is disposed lowest among the color layers.
