Claim Text:
1. A light emitting device comprising: a thin film transistor over a first substrate; an insulating layer over the thin film transistor; a first electrode electrically connected to the thin film transistor; an insulator over the first electrode, the insulator including an opening which overlaps a first portion of the first electrode, wherein a second portion of the first electrode is covered with the insulator; a light emitting layer comprising an organic material overlapping at least the first portion of the first electrode; and a second electrode over the light emitting layer, wherein the light emitting layer is configured to emit light by a current flowing through the first electrode, the light emitting layer and the second electrode, wherein the first portion of the first electrode is thinner than the second portion of the second electrode, wherein an inner edge of the insulator is aligned with a boundary between the first portion and the second portion, and wherein the thin film transistor comprises a channel forming region which comprises polycrystalline silicon.
