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.
