Abstract
A display device includes a first substrate, a first metal layer, a gate insulating layer, semiconductor channels, a second metal layer, a color filter layer, a shielding electrode, an insulating layer, pixel electrodes, a liquid crystal layer, a second substrate and a second common electrode. The first metal layer is located on the first substrate and includes scan lines, gates and first common electrodes. The gate insulating layer is located on the first metal layer. The semiconductor channels are located on the gate insulating layer. The second metal layer is located on the gate insulating layer, and includes sources, drains and data lines. The color filter layer is located on the second metal layer. The shielding electrode at least partially overlaps the second metal layer. The insulating layer is located on the color filter layer. The second common electrode is located on the second substrate.
