Abstract
A color filter type EL display device in which the deterioration of a light-emitting layer is prevented, which can be manufactured by a gang-printing method, and whose cost in manufacture is reduced includes: a display area having a plurality of pixels; a frame area surrounding the display area; lower electrodes each formed in each of pixels; an insulating layer separating the pixels; a light-emitting EL layer formed on the lower electrodes and the insulating layer so as to straddle the plurality of pixels; an upper electrode formed on the EL layer so as to straddle the plurality of pixels; and a sealing layer formed on the upper electrode. In the frame area, the upper electrode and the insulating layer contact each other, or the sealing layer and the insulating layer contact each other, so as to surround the display area.
