Claim:
A display apparatus comprising: a display part including a plurality of light guide elements which have end faces, are extended in the column direction, and are arranged in the row direction in parallel with each other; emitting parts which emits light beams which are directed to the end faces and are introduced into the light guide elements, respectively; scanning lines extended in the row direction, arranged in the column direction, and intersecting with the light guide elements; a generation module which generates scanning signals to the scanning lines; a control unit which controls the emitting parts to control emissions of the light beams from the emitting parts into the light guide elements; control elements provided at intersections of the light guide elements and the scanning lines, each of which causes a part of the light beam traveled in the light guide element to the outside of the light guide element in response to the scanning signal applied to the control element through the scanning line; and first transmission lines extended along the light guide elements, which connect the scanning lines to the generation module to supply the scanning signals to the scanning lines from the generation module, respectively.
