Abstract: A Liquid crystal display device and manufacturing method thereof are provided. According to an exemplary embodiment of the present disclosure, an LCD device includes: a first substrate including a display area and a non-display area disposed outside of the display area; a gate electrode disposed on the first substrate and including a first-layer gate electrode and a second-layer gate electrode disposed on the first-layer gate electrode; a pixel electrode disposed on the same layer as the first-layer gate electrode; a source electrode and a drain electrode disposed on the gate electrode to be spaced from each other; and a contact connecting the drain electrode and the pixel electrode and including a first-layer contact, which is disposed on the same layer as the pixel electrode, and a second-layer contact, which is disposed on the first-layer contact.

Abstract: A method for manufacturing a liquid crystal display includes: forming a first passivation layer and an organic layer, forming an edge of an inclined portion of the organic layer by partially removing the organic layer at a location where a first drain contact hole that exposes a drain electrode of a thin film transistor is formed, forming a second passivation layer including a third drain contact hole exposing the drain electrode, a first electrode including a second drain contact hole exposing the drain electrode, and the first drain contact hole through an etching process using one etching mask, and forming a second electrode on the second passivation layer. The first drain contact hole, the second drain contact hole, and the third drain contact hole overlap with each other, and a size of the second drain contact hole is greater than a size of the third drain contact hole.
