Organic light emitting diode display device with micro lenses
First Claim
1. An organic light emitting diode display device comprising:
- a substrate divided into an emissive area and a non-emissive area;
an overcoat layer disposed on the substrate and having a plurality of micro lenses in the emissive area and at least one depression in the non-emissive area, each of the plurality of micro lenses comprising a concave portion and a connecting portion;
a thin film transistor disposed in the non-emissive area and covered by the overcoat layer;
a first electrode disposed on the overcoat layer and connected to the thin film transistor through a contact hole formed in the overcoat layer;
a bank pattern disposed in the non-emissive area so as to be superposed on the at least one depression and the contact hole;
an organic light emitting layer disposed on the first electrode; and
a second electrode disposed on the organic light emitting layer,wherein each of the first electrode, the organic light emitting layer and the second electrode has a shape according to the plurality of micro lenses in the emissive area,wherein the at least one depression has a different shape from a shape of the concave portion, andwherein the at least one depression surrounds the emissive area in a plan view.

Abstract
Disclosed is an organic light emitting diode display device. The disclosed organic light emitting diode display device includes an overcoat layer disposed on a substrate that is divided into an emissive area and a non-emissive area, and has multiple micro lenses in the emissive area and at least one depression in the non-emissive area. The organic light emitting diode display device further includes: a first electrode disposed on the overcoat layer, wherein the first electrode is disposed in the entire emissive area and in a part of the non-emissive area; a bank pattern disposed in the non-emissive area so as to be superposed on the depression; an organic light emitting layer disposed on the substrate; and a second electrode disposed on the organic light emitting layer. Accordingly, the organic light emitting diode display device may prevent light leakage.
