<p>PURPOSE: A liquid crystal display and a manufacturing method thereof are provided, in which the display has a high mobility in the channel region and realizes high transmittance and high speed driving. CONSTITUTION: A liquid crystal display comprises an insulating substrate(10), a gate electrode(24), an oxide semiconductor layer(40), an etch stopper layer(50), a common electrode(52), source electrodes(55,65), drain electrodes(56,66), a protection film(70), and a pixel electrode(82). In the insulating substrate, the common electrode line transferring the common voltage is formed in the upper part. The gate electrode is formed on the insulating substrate. The oxide semiconductor layer is formed on the gate electrode. The etch stopper layer is formed on the channel region of the oxide semiconductor layer. The common electrode is formed on the insulating substrate. The protection film is formed on the etch stopper layer, the common electrode, and the source electrode and drain electrode.</p> |
