Abstract

An organic EL display panel with improved visibility is disclosed which includes sub-pixels each emitting light of a color selected from R, G, and B and disposed in a matrix, pixel electrodes disposed above a substrate in the matrix corresponding to the sub-pixels, and column banks row-directionally arranged extending in the column direction. The organic EL display panel further includes pairs of auxiliary column banks extending parallel to the main column banks, disposed in gaps between pairs of the column banks adjacent to each other where the pixel electrodes corresponding to the sub-pixels emitting the B color are present, each pair of the auxiliary column banks covering both edges in the row direction of each of the pixel electrodes therebetween.
