    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.

    摘要翻译： 本发明通过防止诸如电源线的扩大，上下电容器电极的加宽引起的开口率的降低来提供包括有机发光（LE）元件的顶部发射型的OLED 以及由平坦化层的粗糙度引起的上下电极之间的短路。 提供了两种OLED。 一个是在用于驱动像素的TFT的电源线上形成包括夹在上电极和下电极之间的LE层的区域的OLED。 另一个包括形成在连接到TFT的电容器的电极上的LE层的区域，以控制发光元件。 因此，在发光层上不形成平坦化层的情况下，在下部电极和上部电极之间不存在电气短路。

    摘要： An active matrix type display includes a light emission device having a transparent pixel electrode and a metal pixel electrode on both surfaces of a light emitting layer and a driving circuit controlling the driving current of the light emission device. The driving circuit is formed on a substrate, and the light emission device is formed as a layer above the driving circuit with an intermediate layer of insulation material interposed therebetween. The metal pixel electrode device is connected with the driving circuit through a conduction portion which extends through the intermediate layer. Thus, light emitted from the light emission device can be prevented from reaching transistors by locating the transistors below the metal pixel electrode, and leakage current produced by the light of a transistor in the off state can be suppressed to prevent degradation of the image quality.

    摘要： The pixels of a top emission display include a light emission device having a transparent pixel electrode and a metal pixel electrode on both surfaces of a light emitting layer and a driving circuit controlling the driving current of the light emission device. The driving circuit is formed on a substrate, and the light emission device is formed as a layer above the driving circuit with an intermediate layer of insulation material interposed therebetween. The transparent pixel electrode is situated opposite to the substrate. The metal pixel electrode device is connected with the driving circuit through a conduction portion which extends through the intermediate layer. Thus, light emitted from the light emission device can be prevented from reaching transistors by locating the transistors below the metal pixel electrode, and leakage current produced by the light of a transistor in the off state can be suppressed to prevent degradation of the image quality.
