Display device, electronic apparatus, and method of fabricating the display device
It is an object of the invention to provide a technique to manufacture a display device with high image quality and high reliability at low cost with high yield. The invention has spacers over a pixel electrode layer in a pixel region and over an insulating layer functioning as a partition which covers the periphery of the pixel electrode layer. When forming a light emitting material over a pixel electrode layer, a mask for selective formation is supported by the spacers, thereby preventing the mask from contacting the pixel electrode layer due to a twist and deflection thereof. Accordingly, such damage as a crack by the mask does not occur in the pixel electrode layer. Thus, the pixel electrode layer does not have a defect in shapes, thereby a display device which performs a high resolution display with high reliability can be manufactured.
