Abstract: An absorption axis of the second polarizing plate provided on a counter substrate is parallel to an alignment axis of the liquid crystal molecules of a liquid crystal layer, the biaxial retardation film is arranged such that a slow axis of the biaxial retardation film forms a first angle formed counterclockwise with the absorption axis or formed clockwise with the alignment axis in a plane of the liquid crystal panel, and a transmission axis of a first polarizing plate provided on an array substrate is arranged such that the transmission axis of the first polarizing plate forms a second angle larger than the first angle from the absorption axis or the alignment axis in the same direction as the first angle in the plane of the liquid crystal panel.

Abstract: The vibrating element generates vibration in the touch panel. In the display apparatus, there exist three directions including an x-axis direction and a y-axis direction along the display surface and a z-axis direction orthogonal to the display surface. The plurality of supports are configured such that touch panel does not move in the x-axis direction and the z-axis direction being two directions included in the three directions. Of the three directions, the direction other than the two directions coincides with a vibration direction being a direction of vibration generated by the vibrating element. The touch panel is configured so that the touch panel is configured to move in the vibration direction.

Abstract: A texture display device includes a display unit in which each pixel includes a condensing type element having light distribution at a first spread angle and a diffusing type element having light distribution at a second spread angle larger than the first spread angle, a pixel signal generation unit that generates a pixel signal based on image data and texture data of an object to be displayed on the display unit, and a control unit that controls light emission intensity of the condensing type element and the diffusing type element based on the pixel signal.

Abstract: A multi-display includes a display panel array with the display panels arranged, and a protective plate disposed over a surface of the display panel array where light is emitted, so as to cover the display panel array. The protective plate has an optical refractive device of groove shape disposed in a position corresponding to a joint between the adjacent display panels of the display panel array, so as to extend along the joint. The optical refractive device refracts the light from the display panels. Each display panel has a display surface having sub-pixels constituting individual pixels. The sub-pixels are arranged in such a manner that the sub-pixels of two or more different display colors are disposed between the sub-pixels of the same display color. The sub-pixels of the display panels adjacent to each other via the joint are arranged in such a manner that color arrangements are different from each other at panel ends facing each other via the joint.
