Abstract
In a liquid crystal TV set, a liquid crystal panel includes an image display section constituted by a liquid crystal for displaying an image and a peripheral portion of the image display section having horizontal and vertical scanning circuits for driving the liquid cyrstal. A operating unit having a plurality of switches is arranged on the front of the peripheral portion. The switches of the operating unit includes at least a thin key switch are are arranged in matrix. This construction permits the liquid crystal panel to be arranged in the same plane as the operating unit, reducing both the size of a liquid crystal TV set and the number of assembly steps thereof at the same time.

17. A method of fabricating a liquid crystal TV set comprising a top case, a center case and a bottom case;
-
said method comprising the steps of; setting operating means having a plurality of switches in position on the top case by at least a stepped portion of the top case; setting a liquid crystal panel in position on the top case by a protrusion formed on the top case; setting the top case in position by at least a stepped portion formed on the outer periphery of the center case; holding the operating means and the liquid crystal panel between the top case and the center case by fixing the top case and the center case; fixing a back liquid unit including a back light, a diffusion plate and a reflector on the center case; and fixing the bottom case having at least a circuit board fixed therein, on selected one of the top case and the center case.
