The present invention provides OLEDs of the top emission type comprising
organic light-emitting (LE) elements by preventing the problems such as
the widening of the power lines, the reduction in the aperture ratio
caused by the widening of the upper and the lower capacitor electrodes
and the short circuit between the upper and the lower electrodes caused
by the roughness of the flattening layers. Two kinds of the OLEDs are
provided. One is an OLED comprising a region of LE layer sandwiched
between the upper and lower electrodes is formed on a power line of TFT
for driving the pixel. Another comprises a region of the LE layer formed
on an electrode of capacitor connected to the TFTs to control the
light-emitting element. Accordingly, without forming a flattening layer
on the light-emitting layer, there is no electric short circuit between
the lower electrode and the upper electrode.
