THIN-FILM TRANSISTOR ARRAY SUBSTRATE, ORGANIC LIGHT EMITTING DISPLAY DEVICE COMPRISING THE SAME AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: A thin film transistor array substrate, an organic light emitting display device, and a manufacturing method thereof are provided to prevent a leakage current between a top electrode and a bottom electrode by forming a protection layer in a region without an insulation layer outside a bottom electrode. CONSTITUTION: A thin film transistor includes an active layer(212), a gate electrode, a source electrode(216a), and a drain electrode(216b). A capacitor includes a top electrode and a bottom electrode. A first insulation layer(13) is formed between the top electrode and the bottom electrode. A second insulation layer(15) is formed between the first insulation and the source and drain electrodes. A protection layer(17) is formed outside the bottom electrode.
