Organic light emitting display device

摘要

The present invention provides a display device which can realize the easy quality control of a display panel thus enhancing the quality and the reliability of the manufacturing of the display device. To achieve the object, the display device includes a light transmitting glass substrate SUB1 which has a display region AR formed of a pixel circuit in which a large number of display pixels SP each of which is constituted of a light emitting element and an active element are arranged in a matrix array on a main surface thereof; and a sealing glass substrate SUB2 which covers the main surface of the light transmitting glass substrate SUB1 and is hermetically sealed to a peripheral portion of the light transmitting glass substrate SUB1 with a sealing agent SEL therebetween. A dummy pixel DP which is constituted of a light emitting element and a passive element is arranged outside the display region AR on the main surface of the light transmitting glass substrate SUB1. The display pixels SP and the dummy pixel DP are formed by sequentially stacking anodes AD, organic multilayered films ELM and cathodes KD on the main surface of the light transmitting glass substrate SUB1 respectively. In the dummy pixel DP, the organic multilayered film ELM is exposed by removing at least a portion of the cathode KD, and an electric current path is formed between a remaining other portion of the cathode KD and the anode AD.
