Abstract

A display device comprises: a base layer including a display region and a non-display region; and a plurality of pixels provided in the display region and each having a plurality of sub-pixels. According to one embodiment of the present invention, each sub-pixel may comprise a display element layer including a pixel circuit unit, a light emitting region for emitting light, and a non-light emitting region provided around the light emitting region. The display element layer may comprise: a partition provided in the light emitting region of each sub-pixel; a bank provided in the non-light emitting region of each sub-pixel and located on the same surface as the partition; first and second electrodes provided on the partition and spaced apart from each other; and at least one light emitting device provided between the first and second electrodes in the light emitting region of each sub-pixel and emitting light.

Description

technical field [0001] Various embodiments of the present disclosure relate to a display device, and more particularly, to a display device including an ultra-small light emitting element and a method of manufacturing the same. Background technique [0002] Light-emitting diodes can have relatively satisfactory durability even under harsh environmental conditions, and have excellent performance in terms of lifespan and brightness. Recently, research on techniques for applying such light emitting diodes to various display devices has become remarkably more active. [0003] As part of such research, a technique of using an inorganic crystal structure (for example, a structure obtained by growing a nitride-based semiconductor) to manufacture a light-emitting diode having an ultra-miniature size corresponding to the micro- or nano-order is being developed. [0004] Light emitting diodes can be fabricated in a size small enough to form pixels of display devices and the like. Th...
