The OELD has a concave portion or a convex portion for enlarging a surface such that the substantial area of an organic light emitting material increases. Thus, an effective light emission area increases in a pixel having a limited area and light emission of desired high brightness can be performed by a low driving voltage. A reduction in a driving voltage causes improvement in the durability of a pixel and the life span of the OELD is enlarged.
