Abstract: A color organic EL display is provided with first electrodes extending in a column direction, second electrodes extending in a row direction, pixels arranged in a row direction and a column direction, and an organic luminescence layer between the first electrode and the second electrode which emits luminescence by applying a voltage to the first and the second electrodes to make an electric current flow therebetween. The number of the first electrodes is twice of the number of displaying columns. The second electrode is provided at every two displaying rows. Each of the pixels consists of three sub pixels for three luminescence colors arranged in order in the row direction. Each of the sub pixels is provided in each of regions where the first electrodes intersect with the second electrodes in a plan view. The sub pixels are arranged while being shifted to each other by a half pitch in the row direction between adjacent two displaying rows.

Abstract: An organic thin film EL panel includes a plurality of transparent electrodes, an organic film, and a plurality of metal electrodes. The transparent electrodes are formed into stripes on a transparent substrate. The organic film includes a light-emitting layer and is formed on the transparent substrate and the transparent electrodes. The plurality of metal electrodes are formed into stripes on the organic film in a direction perpendicular to the transparent electrodes. The metal electrodes are comprised of a plurality of electrode portions arranged at a predetermined interval, and a plurality of interconnections that connect adjacent ones of the electrode portions to each other. The electrode portions have pixel regions where the metal electrodes and the transparent electrodes overlie each other, and connection regions other than the pixel regions. The interconnections connect the connection regions of adjacent ones of the electrode portions to each other.

Abstract: A method for manufacturing an organic EL display device is provided, capable of improving an opening ratio and providing narrower pitches for narrowing non-lighting portion between pixels, and, at the same time, capable of eliminating short-circuiting between display pixels for eliminating cross-talk and non-lighting pixels. In the deposition process of the cathode 6, the incident angle of the deposition material onto the substrate is optimized by optionally changing parameters such as a distance between the substrate 1 and the mask 11 and a distance between the substrate and the point deposition source 13. Thus, deposition material from a plurality of deposition sources impinges onto the substrate surface obliquely passing at a different incident angles though opening (slits 11a) of the mask 11, so that the width 10 of the electrode pattern 6 becomes broader than the width of the slit by superposition of the deposition material passing through the slits at different incident angles.
