Abstract
In an organic EL display device including a TFT (40) and an organic EL element (60) formed on an insulating substrate (10) of a glass substrate, insulating films, namely, a planarization insulating film (17), an interlayer insulating film (15), and a gate insulating film (12), for forming the TFT (40) are not provided at a region for forming the organic EL element (60). Instead, an opening (65) formed by removing these insulating films is provided to expose the glass substrate (10), and at this exposed region an anode (61), an emissive element layer (62), and a cathode (63) are formed in this order. Consequently, light emitted from the emissive element layer (62) is prevented from reflecting at interfaces between these insulating films (12, 15, and 17), and efficiently exits from the glass substrate (10) side.
