摘要:
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.
