ABSTRACT:
A light-emitting device having a structure in which a mask used for forming a film such as an organic compound layer does not come in contact with the pixels in forming the light-emitting elements, and a method of fabricating the same. In fabricating the light-emitting device of the active matrix type, a partitioning wall constituted by a second wiring and a separation portion is formed on the interlayer-insulating film, and the pixels are surrounded by the partitioning wall, preventing the mask from coming into direct contact with the pixels, the mask being used for forming the organic compound layer and the opposing electrode of the light-emitting elements.
