Abstract
This display module prevents the leakage current generated between a first electrode layer and a second electrode layer that constitute a pixel via an organic light emitting layer and obtains uniform luminance. An interlayer insulation layer ILI is provided between an edge of a first electrode layer AD and an organic light emitting layer OLE that constitute the pixel and the distance between the edge and a second electrode layer CD is secured sufficiently. Further, the interlayer insulation layer ILI is coated with a resin material having fluidity and flatness is improved as a whole. An aperture that accommodates the organic light emitting layer OLE is formed in this interlayer insulation layer ILI and the coated organic light emitting layer OLE is formed in uniform thickness and through a necessary and sufficient spread.
