Filed: 1990-11-13
Abstract: PURPOSE:To reduce bad orientation, in particular at the time of voltage application, in the vicinity of a spacer by using a spacer that has a characteristic of vertical orientation of the surface to a liquid crystal. CONSTITUTION:The orientation condition of a panel which is dispersed in vertical orientation on a spacer surface, is the orientation condition of a spacer 11, of the vicinity of a spacer 12, and of the other part 13, and when the process of vertical orientation is not provided, the orientation condition is for a spacer 61, for the vicinity of the spacer 62, and for the other part 63. A figure (a) indicates the orientation condition where no voltage is applied, and voltages of 2.2V is applied in a figure (b), and 3.0V in a figure (c). When the figure (a) is examined, no difference is shown concerning bad orientation region in the vicinity of the spacer. When the figures (b) and (c) are compared with each other, if the process of vertical orientation is provided, the liquid crystal particle in the vicinity of te spacer is orientated in the same way as the other particle, while if the surface process is not provided, the liquid crystal particle in the vicinity of the spacer is hard to respond to an electric field, and orientation is thus different. The difference in the orientation in the vicinity of spacer is thus reduced.
