A liquid crystal television receiver has a main frame including a reflecting plate and a hood member with a liquid crystal display panel and an electroluminescence panel. The reflecting plate is disposed so as to slant with respect to the liquid crystal display panel, and provides a display of a picture from the display panel in a reflecting manner. The electroluminescence panel is slidably provided in the hood member. For illuminating the liquid crystal display panel, the electroluminescence panel is slid above the liquid crystal display panel.

A portable television reciever of the panel type, having a pocketable size, is provided with about 1/8 the number of scanning electrodes as effective T.V. picture scanning lines, and a panel type picture display device with a double matrix array in which two picture element electrodes lying on each of the signal electrodes commonly provided in the direction of the width of said scanning electrodes are disposed in opposition to each other. A display circuit is driven at a duty cycle expressed as follows: ##EQU1## where A is the number of fields constituting one frame, B is the number of horizontal periods for a video signal assigned to a scanning electrode; and C is the number of scanning lines.
