Abstract: A display device includes a first camera that captures an image of a first viewer present in a first normal direction of a display surface of a transparent display, a second camera that captures an image of a second viewer present in a second normal direction of the display surface of the transparent display, the second normal direction being an opposite direction of the first normal direction, a microphone, and a control circuit that includes a user coordinate calculation circuit, a gesture detection circuit, a dictation circuit, and a drawing information generation circuit. The user coordinate calculation circuit specifies positions of the first viewer and the second viewer on the basis of the images from the first camera and the second camera. When the gesture detection circuit determines that the first viewer utters sound, the dictation circuit generates a character based on sound information from the microphone, and the generated character is displayed on the transparent display toward the second viewer by the drawing information generation circuit.

Abstract: A transparent display includes: a first substrate having a first surface; a second substrate having a second surface; a display layer having pixels that can transition between a transparent state that transmits background light and a display state that displays an image; a display region (screen); a controller; and a sensor device (camera) for detecting a distance between a user on a first surface side and the display region, and a position in the display region. The controller controls a degree of transparency so as to be changed in a partial region corresponding to the position according to the distance from the user to the screen.

Abstract: A liquid crystal display panel for displaying images in an active area includes a first substrate having a pair of first short ends and first long ends. A second substrate faces the first substrate so as to hold a liquid crystal layer therebetween. A first polarization plate is arranged on an outside surface of the first substrate. The first polarization plate has a pair of second short ends longer than the first short ends, a pair of second long ends, and a first absorption axis. The angle a1 made by the first absorption axis with respect to the second short ends is smaller than an angle b1 made by the first absorption axis with respect to the second long ends. A second polarization plate is arranged on an outside surface of the second substrate and has a second absorption axis.
