Abstract
An organic light emitting display device wherein organic and inorganic films are alternately stacked, and the inorganic film is patterned to form an outgassing route, through which gas is released from the organic film, and a manufacturing method thereof is herein.
Claims17
An organic light emitting display device, comprising:
- a cell drive unit having a plurality of pixels on a substrate and comprising at least one transistor between the respective pixels;
- an insulating stack unit comprising an organic film and an inorganic film formed one above the other on the substrate in a region of the cell drive unit;
- wherein the inorganic film of the insulating stack unit corresponding to the cell drive unit is patterned to form an outgassing route, an upper surface of the organic film of the insulating stack unit having an over-etched portion defining a recess at a portion corresponding to the outgassing route;
- an organic light emitting diode connected to the cell drive unit through the insulating stack unit.
