Patent ID: 8829527

Claim:
A display device comprising: a first substrate; a thin film transistor over the first substrate; a first insulating layer over the thin film transistor; a first conductive layer over the first insulating layer, wherein the first conductive layer is electrically connected to the thin film transistor; a second insulating layer containing a first organic material over the first conductive layer; a pixel electrode over the second insulating layer, the pixel electrode being electrically connected to the thin film transistor; a third insulating layer containing a second organic material over a part of the pixel electrode; a light emitting layer comprising an organic compound over the pixel electrode, wherein a portion of the light emitting layer is formed over the third insulating layer; a second electrode over the light emitting layer and the third insulating layer, wherein the pixel electrode is overlapped with the second electrode with the light emitting layer therebetween; a second substrate over the second electrode, the second substrate being fixed to the first substrate with a sealing material therebetween, wherein the first substrate includes a portion which extends beyond a side edge of the second substrate and is not covered by the second substrate; a fourth insulating layer containing the first organic material over the portion of the first substrate; and a fifth insulating layer containing the second organic material over the portion of the first substrate, the fifth insulating layer being formed over the fourth insulating layer.
