ORGANIC LIGHT EMITTING DIODE DISPLAY

摘要

PURPOSE: An organic light emitting display device obtains enough space for a storage capacitor because there is no necessary to form an initialization contact at each pixel. CONSTITUTION: A pixel unit includes a first pixel (R) and a second pixel (Ga) disposed in a first row on a substrate and a third pixel (B) and a fourth pixel (Gb) disposed on a second row. A scan line (121) and a previous scan line (122) apply a scan signal and a previous scan signal to the pixel unit, respectively. A data line (171) and a driving voltage line (172) apply a data signal and a driving voltage to the pixel unit, respectively. A common initialization voltage line (193) applies an initialization voltage to the pixel unit. A storage capacitor (Cst) includes a first capacitive plate (132) and a second capacitive plate (127) disposed across a gate insulating film.
