Abstract
(EN)
A display device is provided. The display device comprises: a first electrode and a second electrode disposed apart from and facing the first electrode; a light blocking layer disposed above the first electrode and the second electrode; and at least one light emitting element disposed between the first electrode and the second electrode. The light blocking layer includes a light blocking part for absorbing light and an opening pattern. The light blocking part includes an electrode-overlapping region that partially overlaps the first electrode and the second electrode. The opening pattern exposes some portions of the mutually facing first and second electrodes and at least a portion of the region between the mutually facing first and second electrodes. The at least one light emitting element can be disposed overlapping the opening pattern.

L'invention concerne un dispositif d'affichage. Le dispositif d'affichage comprend : une première électrode et une seconde électrode disposées à distance de la première électrode et faisant face à la première électrode; une couche de blocage de lumière disposée au-dessus de la première électrode et de la seconde électrode; et au moins un élément électroluminescent disposé entre la première électrode et la seconde électrode. La couche de blocage de lumière comprend une partie de blocage de lumière destinée à absorber la lumière et un motif d'ouverture. La partie de blocage de lumière comprend une région de chevauchement d'électrode qui chevauche partiellement la première électrode et la seconde électrode. Le motif d'ouverture expose certaines parties des première et seconde électrodes se faisant mutuellement face et au moins une partie de la région entre les première et seconde électrodes se faisant mutuellement face. Le ou les éléments électroluminescents peuvent être disposés de manière à chevaucher le motif d'ouverture.
