Abstract

A display device includes a first substrate including a display area and a peripheral area outside the display area, pixels arranged in the display area and each including an emission area defined by a non-emission area, a thin-film encapsulation layer covering the pixels and including at least one inorganic encapsulation layer and at least one organic encapsulation layer, a pattern layer above the thin-film encapsulation layer, the pattern layer including a first light-blocking pattern shielding at least a portion of the non-emission area, and a second substrate facing the first substrate and including a second light-blocking pattern shielding at least a portion of the non-emission area.

Claims (20)

1. A display device comprising:

a first substrate including a display area and a peripheral area outside the display area;

a plurality of organic light-emitting diodes in the display area, each of the plurality of organic light-emitting diodes including a pixel electrode, an intermediate layer, and an opposite electrode;

a thin-film encapsulation layer covering the plurality of organic light- emitting diodes and including a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer that are sequentially stacked;

a buffer layer arranged on the thin-film encapsulation layer and covering the display area and the peripheral area;

a pattern layer on the buffer layer, the pattern layer including a first light- blocking pattern shielding a portion of an area between two adjacent organic light-emitting diodes of the plurality of organic light-emitting diodes and

a terminal arranged in the peripheral area and a connection wiring arranged below the terminal, wherein the buffer layer directly contacts a portion of the terminal, and the buffer layer includes

a first contact hole that exposes the terminal and a width of the terminal is greater than a width of the connection wiring.

2. The display device of claim 1 , further comprising:

an additional terminal layer contacting the terminal through the first contact hole,

wherein the additional terminal layer includes a same material as that of the first light-blocking pattern.

3. The display device of claim 1 , further comprising: the connection wiring extending from the peripheral area to the display area, wherein the connection wiring is connected to the terminal through a second contact hole.

4. The display device of claim 1 , further comprising:

a second substrate facing the first substrate and including a second light-blocking pattern that is vertically aligned to the first light-blocking pattern.

5. The display device of claim 4 , wherein the pattern layer further includes a first opening that is vertically aligned to a corresponding emission area of a plurality of emission areas, the second light-blocking pattern includes a second opening that is vertically aligned to the corresponding emission area of the plurality of emission areas, and an area of the first opening is greater than an area of the second opening.

6. The display device of claim 4 , further comprising: a plurality of quantum emission layers disposed on the second substrate, each of the plurality of quantum emission layers being vertically aligned to a corresponding emission area of a plurality of emission areas and including a quantum dot.

7. The display device of claim 4 , further comprising:

a sealing member arranged in the peripheral area, wherein the first substrate and the second substrate are attached to each other by the sealing member.

8. The display device of claim 1 , wherein the first light-blocking pattern includes metal.

9. The display device of claim 1 , wherein the plurality of organic light-emitting diodes emit blue light.
