Abstract:
1. An organic EL display apparatus comprising: a plurality of organic EL elements each including, in order, a first electrode, an organic EL layer, and a second electrode laminated on an optically transparent supporting substrate; and a display unit including a two-dimensional arrangement of said plurality of organic EL elements on said supporting substrate to define pixels, wherein, for each organic EL element, one of said first electrode and said second electrode is an optically transparent electrode, the other of said first electrode and said second electrode is a non-optically transparent electrode, said non-optically transparent electrode is disposed to only exist in part of each pixel as viewed from vertically above, no electrode for light-emitting except the non-optically transparent electrode is provided on a side of the organic EL layer on which the non-optically transparent electrode is disposed, a background of the display unit is observable through a portion within the pixel in which said non-optically transparent electrode is not disposed, said organic EL elements are arranged in a matrix form on said supporting substrate, said pixel has a square planar shape, said organic EL display apparatus includes a plurality of strip-shaped electrodes extending in parallel with one another with a predetermined interval spaced therebetween as said optically transparent electrodes and said non-optically transparent electrodes, respectively, said optically transparent electrode and said non-optically transparent electrode intersect substantially at right angles within said pixel, as viewed from vertically above, and said non-optically transparent electrode is disposed to extend across a set of opposing sides of said pixel, and has a width smaller than the length of the side.
