Abstract

A display apparatus comprises a display unit which has a plurality of organic EL elements two-dimensionally arranged to define pixels. Each organic EL element comprises a first electrode, an organic EL layer, and a second electrode laminated in order on an optically transparent substrate. One of the first electrode and second electrode is an optically transparent electrode, while the other is a non-optically transparent electrode. The non-optically transparent electrode is disposed to exist only in part of each pixel, as viewed from vertically above (for example, the width of the electrode is made smaller than the width of a pixel). In this way, the display unit can transmit light through portions of the pixels in which the non-optically transparent electrodes are not disposed. Preferably, the non-optically transparent electrode includes a mirror surface opposite to the organic EL layer.
