US 12,255,223 B2 · Display device, and method for producing same

Abstract

A display device includes a pixel in a display area. The pixel includes: spaced apart first and second electrodes; a first insulating layer on the first electrode and the second electrode and between the first electrode and the second electrode and having a first etch selectivity; a first insulating pattern on the first insulating layer between the first electrode and the second electrode, and having a second etch selectivity; a light emitting element on the first insulating pattern; a second insulating pattern having the second etch selectivity and being on one area of the light emitting element such that a first end and the second end of the light emitting element are exposed; and third and fourth electrodes configured to electrically connect the first end and the second end of the light emitting element to the first and second electrodes, respectively.
