Array substrate and display device comprising the same

摘要

An array substrate, which is formed with a gate electrode (2), a source electrode (5), a drain electrode (6), a gate insulating layer (3), an active layer (4) and a passivation layer (9) in a thin film transistor region, and with the gate insulating layer (3), a pixel electrode (7), the passivation layer (9) and a common electrode (8) in a pixel electrode pattern region, and a color resin layer (11) is formed between the passivation layer (9) and the common electrode (8). Since the color resin layer (11) for planarization is formed on the passivation layer (9), the horizontal driving manner may be suitably applied in order to reduce light leakage, to improve contrast ratio and aperture ratio of a panel and to lower production costs.
