Organic electro-luminescence display apparatus and organic thin film transistor for the same
First Claim
1. An organic electro-luminescence display apparatus comprising:
- a first electrode layer which supplies holes;
a second electrode layer which supplies electrons;
an organic thin film layer disposed between the first electrode layer and the second electrode layer, the organic thin film layer emits light through the recombination of the holes and the electrons; and
a sealing protection layer which insulates at least the second electrode layer and the organic thin film layer from an external gas, wherein the sealing protection layer comprises at least a LaF3 layer.

Abstract
An organic electro-luminescence display apparatus and an organic thin film transistor for the same include: a first electrode-layer supplying holes; a second electrode layer supplying electrons; an organic thin film layer disposed between the first electrode layer and the second electrode layer, the organic thin film layer emits light through the recombination of the holes and the electrons; and a sealing protection layer insulating at least the second electrode layer and the organic thin film layer from an external gas, wherein the sealing protection layer includes at least a LaF3 layer. Since the penetration of harmful materials such as moisture or oxygen is prevented, the organic electro-luminescence display apparatus can provide constant performance. In addition, since an additional sealing structure is not required, the organic electro-luminescence display apparatus is lighter, thinner, and less costly to manufacture.
