Abstract: A method including: forming a thin-film transistor array device that constitutes a pixel circuit; forming light-emitting layers; and after forming a light-emitter by forming the light-emitting layers, sealing the light-emitter entirely. The forming of the light-emitting layers includes: preparing transfer substrates, each transfer substrate having a supporting substrate on which a transfer layer including at least one of red, green, and blue light-emitting materials is formed; and transferring the corresponding transfer layer onto a transfer-target substrate of an EL display device by using the corresponding transfer substrate, and the forming of the light-emitting layers, the sealing, and the forming of the transfer layer of each transfer substrate are performed within an isolation atmosphere for preventing exposure to the air.

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.
