ABSTRACT:
In a display device having a display region formed by disposing a plurality of organic light emitting elements such as organic EL elements, it becomes possible to prevent penetration of water into the display region to suppress degradation in display characteristics even during drive over a long period of time and to improve long-term reliability. There is provided a display device comprising a display region (120) having a plurality of organic light emitting elements disposed on a substrate (101), each of the plurality of organic light emitting elements having an organic layer (103comprising a light emitting layer interposed between an anode and a cathode (102, 104), wherein the display region (120) is formed on a first insulating protective layer (106) provided on the substrate (101), and a surface on a side opposite to a substrate (101) side and an entire periphery of the display region (120) are covered with an insulating protective film (107).
