Abstract: A display device is provided. The display device includes a first base substrate, a gate line on the first base substrate and extending in a first direction, a data line disposed on the first base substrate, insulated from the gate line, and extending in a second direction, which crosses the first direction, a switch on the first base substrate and electrically connected to the gate line and the data line, an insulating layer on the switch, a first electrode on the insulating layer, a light-shielding conductive layer directly contacting the first electrode and overlapping the switch, and a second electrode insulated from the first electrode and the light-shielding conductive layer, at least partially overlapping the first electrode, and electrically connected to the switch.

Abstract: A method for manufacturing a liquid crystal display, including: preparing a substrate on which a switching element, laminating a conductive material layer and a conductive metal layer, forming a first photosensitive film pattern on the conductive metal layer, the first photosensitive film pattern comprising a first region having a first thickness and a second region having a second thickness greater than the first thickness, forming a conductive metal pattern by etching the conductive metal layer using the first photosensitive film pattern as a mask, forming a second photosensitive film pattern that exposes a part of the conductive metal pattern by removing the first region of the first photosensitive film pattern, forming a common electrode by etching the conductive material layer by using the conductive metal pattern as a mask and forming an auxiliary electrode by etching the exposed conductive metal pattern using the second photosensitive film pattern as a mask.
