Abstract: A light-emitting element display device includes: a thin film transistor substrate including transistors respectively controlling the amounts of light emission of a plurality of sub-pixels arranged in a display region; and a color filter substrate arranged to overlap with the thin film transistor substrate. The thin film transistor substrate includes a light-emitting organic layer covering the entire display region and emitting light in respective light-emitting regions in the plurality of sub-pixels, an insulating bank formed of an insulating material around each of the light-emitting regions, including an inclined surface being closer to the color filter substrate according to increasing in thickness with increasing distance from the light-emitting region, and a fluorescent layer formed on the inclined surface and excited by light of the light-emitting region to thereby emit light.

Abstract: A manufacturing method of a display device is provided. The manufacturing method includes: forming a first electrode over a substrate; forming an organic layer over the first electrode; and forming a second electrode over the organic layer by sputtering a target including a conductive oxide with a light-transmitting property. A mask is arranged between the organic layer and the target when the second electrode is formed. The mask has periodically arranged through holes with a maximum width equal to or larger than 0.1 μm and equal to or smaller than 3 μm.
