ORGANIC LIGHT EMITTING DISPLAY APPARATUS AND MANUFACTURING METHOD THEREOF |
摘要 |
<p>PURPOSE: An organic light emitting display device and a manufacturing method thereof are provided to improve light extraction efficiency and color reproduction by forming a DBR(Distributed Bragg Reflector) resonant structure through a plurality of layers with different refractive indexes. CONSTITUTION: An organic light emitting device includes a first insulation layer(13), a second insulation layer(15), a third insulation layer(118), a pixel electrode(119), an opposite electrode(123), and an organic light emitting layer(122). The first insulation layer and the second insulation layer include an uneven part(116) with a protrusion(116b). The light emitting layer is arranged between the pixel electrode and the opposite electrode. A thin film transistor includes an active layer(212), a gate electrode(214), a source electrode(220a), and a drain electrode(220b). A capacitor includes a bottom electrode(314), a top electrode(319), and a dielectric layer(318). The bottom electrode is arranged on the same layer as the gate electrode. The top electrode is arranged on the same layer as the pixel electrode.</p> |
