Display device having bank directly on and partially in opening of insulating layer and bank surrounding light emitting elements for outgassing

Abstract

A display device includes electrodes on a base layer; a first insulating layer on the electrodes; a bank on the first insulating layer, protruding in a thickness direction of the base layer, and surrounding a region; light emitting elements in the region on the base layer; and connection electrodes electrically connected to the light emitting elements. The connection electrodes include an anode connection electrode electrically connected to the light emitting elements, a cathode connection electrode electrically connected to the light emitting elements, and an extension connection electrode on the bank. The first insulating layer forms at least one first opening. The at least one first opening overlaps the extension connection electrode in a plan view.
