Abstract: A device for displaying a stereoscopic image in which cross-talk is suppressed. A left eye image and a right eye image alternately displayed on a liquid crystal display panel are viewed through an eye shutter having a left eye and a right eye shutter which are alternately switched.

The left eye image is displayed in the first field during which all scanning electrodes in both parts are scanned, and the right eye image is similarly displayed in the second field following the first field. A certain time interval is provided between the first and second fields, while properly setting the eye shutter switching timing.

Abstract: A first electrode plate and a second electrode plate are overlapped on each other with a seal member and spacer walls interposed therebetween. The cell gap formed between both plates is filled with liquid crystal such as smectic liquid crystal. To eliminate orientation disturbance of the liquid crystal caused in the filling process, the liquid crystal flow coming from the down stream of the display area through passages outside the display area (turn-around flow) is eliminated. Dam walls for preventing the liquid crystal flow through the outer passages or structures for reducing the flow speed are formed in the outer passages. Alternatively, the filling passages in the display area are separated from the outer passages. Thus, the liquid crystal is correctly oriented in the display area, thereby achieving uniformity of images displayed.

Abstract: A matrix liquid crystal display is capable of displaying a still displayed picture by using a hysteresis characteristic of an antiferrodielectric liquid crystal medium or the like. The picture is displayed by applying scan signals from a row driving circuit and data signals from a column driving circuit to a matrix liquid crystal display having an antiferrodielectric liquid crystal medium or the like. When a voltage for stilling the display of the picture is provided to a still signal input terminal, a timing circuit interrupts the application of a clock signal output from a control circuit to the row driving circuit in response to a generated vertical synchronizing signal. When the clock signal is stopped, a holding voltage is applied to each pixel of the liquid crystal display and the displayed picture is put into a still state by the hysteresis characteristic of the antiferrodielectric liquid crystal medium or the like.
