Abstract
An organic EL display panel including pixel electrodes above a substrate in a matrix, column banks above the substrate at least between edges of the pixel electrodes in a row direction, extending in a column direction and side-by-side in the row direction, organic light emitting layers continuous in the column direction in gaps between the column banks, and a counter electrode layer above the organic light emitting layers. Width in the row direction of the organic light emitting layers, which is defined by width of the gaps between the column banks, changes at intervals in the column direction. For each of the light emitting layers, a minimum interval is equal to or less than a pitch in the column direction of the pixel electrodes and the changes are different from others of the light emitting layers.
