Abstract:
A touch-panel equipped liquid crystal display apparatus having a display surface comprising: a polarizing plate A; a Â¼ wave plate a having a first film surface and a first slow axis within the first film surface; a touch panel; a Â¼ wave plate B having a second film surface and a second slow axis within the second film surface; and a liquid crystal cell that emits a light having a polarization axis extending in a direction, all disposed in the aforementioned order from the display surface, wherein:the first slow axis within the first film surface of the Â¼ wave plate A is in a horizontal direction of 0Â° or in a vertical direction of 90Â° as viewed from the display surface; the second slow axis within the second film surface of the Â¼ wave plate B is substantially at a diagonal position to the direction in which the polarization axis of the light emitted from the liquid crystal cell extends; and the first slow axis of the Â¼ wave plate A and the second slow axis of the Â¼ wave plate B are nonparallel with each other without crossing at right angles.
