Abstract

A display device including a substrate having a display area including a plurality of pixels and a peripheral area positioned outside the display area, a sealant in the peripheral area, a first spacer on the sealant, an encapsulation substrate on the first spacer, and a touch sensor on the encapsulation substrate facing the display area.

First claim

What is claimed is:

1. A display device, comprising:
a substrate having a display area including a plurality of pixels and a peripheral area positioned outside the display area, wherein the pixels each include:
a transistor,
a first electrode connected with the transistor,
an organic emission layer on the first electrode, and
a second electrode on the organic emission layer;

a sealant on the substrate in the peripheral area;
a first spacer on the sealant, the first spacer being made of a transparent insulating material;
an encapsulation substrate on the first spacer, the transparent insulating material of the first spacer being between the sealant and the encapsulation substrate;
a touch-panel including touch sensors on the encapsulation substrate facing the display area; and
a plurality of second spacers between the touch-panel and the second electrode, wherein each second spacer is made of the transparent insulating material.

2. The display device as claimed in claim 1 , wherein:
the first spacer is on the entire substrate.

3. The display device as claimed in claim 1 , wherein:
the transparent insulating material includes PbO, SnO, V 2 O 5 , P 2 O 5 , BaO, ZnO, B 2 O 3 , or Bi 2 O 3 .

4. The display device as claimed in claim 1 , further comprising a pixel defining layer formed on the substrate and having an opening exposing the first electrode, wherein the second spacer is positioned in a region corresponding to the pixel defining layer.

5. The display device as claimed in claim 4 , wherein:
the second spacer has a column shape.

6. The display device as claimed in claim 4 , wherein:
the pixels are provided in a matrix form, and
the second spacer is provided along at least one of the pixel row and the pixel column to have a linear shape.

7. The display device as claimed in claim 1 , wherein:
the touch sensor is a capacitive type touch sensor.
