Abstract

PURPOSE: To provide a display panel for games which employs liquid crystals having specific problems and which secures good display quality at least for players who take up their positions at opposite side of a game panel.
CONSTITUTION: In a display panel for games such as "go" wherein two or more players take up their positions at opposite sides of a game panel, a display system of twisting type caused by nematic liquid crystals is employed. In such a display panel, a bisector X-X' of angles between axes of the molecules of liquid crystals located at the interface between an upper base plate 32 of the display panel and a layer 33 of liquid crystals and axes of the molecules of liquid crystals located at the interface between a lower base plate 32' and the layer of liquid crystals, the bisector X-X' excluding an axis Y-Y' of the molecules of liquid crystals in the layer, is coincided with a longitudinal axis of ruled lines 52 on the display panel 50 for games. Players 53, 53' watch a liquid crystal panel 52 from a direction O-X or O-X' so that they can see rather well contrasted display.
