Abstract: An EL display device according to the present technology includes a light emitter in which an array of pixels are arranged, each of the pixels including sub-pixels configured to emit at least red, green, and blue light; and a thin film transistor array configured to control light emission of the light emitter. The sub-pixels include light-emitting layers, the light-emitting layers being configured to emit at least red, green, and blue light and being disposed within areas defined by a bank having a lattice shape. Among the sub-pixels, sub-pixels that are adjacent and configured to emit identical colors include one of the light-emitting layers disposed within a first coupled bank area, the first coupled bank area corresponding to an area defined by the bank of two of the sub-pixels.

Abstract: A method of manufacturing an organic electroluminescence display panel includes forming pixel electrode layers in a matrix on a substrate. The method includes arranging column banks extending in a column direction above the substrate. The method includes applying ink containing organic light emitting material to gaps between the column banks so that the ink is continuous between ends of the column banks in the column direction. The method includes arranging the substrate and a rectifying plate facing each other, the rectifying plate having a uniform density of through holes, such that the rectifying plate is at a predefined distance from the column banks. The method includes exhausting gas from an environment including the substrate and the rectifying plate. The method further includes heating the substrate to dry the ink to form an organic functional layer. The method includes forming a counter electrode layer above the organic functional layer.

Abstract: An organic EL display panel including organic light emitting layers, each continuous in a column direction, in gaps between column banks. The organic light emitting layer in a gap end region extending in the column direction from a column direction end of the gap to a reference position a defined distance from the column direction end towards a display region and within a peripheral region has a volume greater than volumes of the organic light emitting layers in gap end regions extending in the column direction from column direction ends of the gaps to the reference position.
