Claims (1)

[Scope of utility model registration request] In a twisted alignment type liquid crystal display device, by making the orientation treatment direction applied to two opposing electrode plates slightly larger than 90°, the twist direction of the liquid crystal molecules interposed in the gap between the electrode plates can be adjusted. is set to a twist angle slightly smaller than 90° in the direction opposite to the twist direction indicated by the orientation treatment direction, and is driven by applying an alternating current voltage between the electrode substrates. A liquid crystal display device characterized in that the light absorption axis direction of the opposing polarizing plates is parallel or perpendicular to the alignment direction of the electrode plate.
