Abstract

Disclosed is a display device including: a substrate; a first electrode on the substrate; a partition wall on the first electrode, the partition wall including a first opening overlapping the first electrode; a touch detection electrode on the partition wall; a low refractive layer on the partition wall and the touch detection electrode, the low refractive layer including a second opening overlapping the first opening; and a high refractive layer on the low refractive layer. The planar shapes of the first opening and the second opening are polygons each including a series of sides, and in a plan view, a distance between one side of the first opening and the second opening is different from a distance between another side of the first opening and the second opening.

Description

[0001] This application claims priority and benefit from Korean Patent Application No. 10-2020-0022890 filed with the Korean Intellectual Property Office on February 25, 2020, the entire contents of which are hereby incorporated by reference. technical field [0002] The present disclosure relates to a display device. Background technique [0003] As a device that displays a screen, the display device includes a liquid crystal display (LCD), an organic light emitting diode (OLED) display, and the like. Such display devices are used in various electronic devices such as cellular phones, navigation devices, digital cameras, electronic books, portable game machines, or various terminals. [0004] The display device is formed of a multilayer structure. For example, a display device may be formed of a multilayer structure in which light emitting elements, touch sensors, etc. are stacked on a substrate. A picture may be displayed by light emitted from the light emitting element ...
