Embodiment Construction

[0045] In this specification, it will be understood that when an element (or region, layer, section, etc.) is referred to as being "on," "connected to," or "coupled to" another element, that element It may be directly on or directly connected or coupled to the other element, or there may be a third element in between.

[0046] Like reference numerals refer to like elements throughout. In addition, thicknesses, proportions, and sizes of elements in the drawings are exaggerated for effective description of technical contents.

[0047] As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0048] The terms "first", "second", etc. may be used to describe various elements, but these elements should not be construed as being limited by these terms. These terms are only used to distinguish one element from other elements. For example, a first element could be termed a second element and vice versa without departing from...

Abstract

A display device comprises: a display panel including a plurality of pixel regions; a first insulation layer disposed on the display panel, having a first refractive index, and having a plurality of first openings defined in regions which overlap the plurality of pixel regions; a second insulation layer directly disposed on the first insulation layer and having a plurality of second openings defined in regions which correspond to the plurality of first openings; and a third insulation layer for covering the display panel, the first insulation layer, and the second insulation layer and having a second refractive index which is higher than the first refractive index, wherein the third insulation layer may overlap, on a plane, the plurality of pixel regions.

Description

technical field [0001] The disclosure here relates to a display device with improved light efficiency and a method of producing a display device with improved process reliability. Background technique [0002] Display devices may be classified into self-luminous display devices in which light emitting elements emit light by themselves or light-receiving display devices that control transmittance of received light. The self-luminous display device may be, for example, an organic light-emitting display device. Light generated in the light emitting layer of the organic light emitting display device may be emitted not only in the front direction but also in the side direction. The light efficiency can be determined based on the light emitted in the frontal direction. That is, light emitted in a side direction may result in a decrease in light efficiency. Contents of the invention [0003] technical problem [0004] The present disclosure provides a display device having im...
