Abstract
An organic light emitting display device includes: a substrate; a display unit on the substrate; and an encapsulation layer on the display unit, the encapsulation layer including a plurality of inorganic layers and a plurality of organic layers, the plurality of inorganic layers and the plurality of organic layers being alternately located, and the plurality of organic layers being at a region where the plurality of inorganic layers is located. The plurality of inorganic layers covers the display unit and is sequentially on the substrate, and areas of each of the inorganic layers are increased moving in a direction away from the display unit.
Claims23
An organic light emitting display device, comprising:
- a substrate;
- a display unit on the substrate;
- and
- an encapsulation layer on the display unit,
- wherein the encapsulation layer comprises a plurality of inorganic layers and a plurality of organic layers, the plurality of inorganic layers and the plurality of organic layers being alternately located, and the plurality of organic layers being at a region where the plurality of inorganic layers is located,
- wherein the plurality of inorganic layers covers the display unit and is sequentially on the substrate, and areas of each of the inorganic layers are increased in a direction away from the display unit, and
- wherein an edge of the encapsulation layer comprises the plurality of inorganic layers sequentially on the substrate, and in the plurality of inorganic layers, an upper inorganic layer covers an end of a lower inorganic layer.
A manufacturing method of an organic light emitting display device, the method comprising:
- forming a display unit on a substrate;
- and
- forming an encapsulation layer on the display unit, wherein the forming of the encapsulation layer comprises:
- forming a first inorganic layer on the display unit;
- and
- laminating organic layers and inorganic layers on the first inorganic layer in sequence, the organic layers being in a region where the inorganic layers are disposed,
- wherein areas of each of the inorganic layers are increased in a direction away from the display unit, and
- wherein an edge of the encapsulation layer comprises the inorganic layers sequentially on the substrate, and in the inorganic layers, an upper inorganic layer completely covers a lower inorganic layer.
