LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

摘要

A liquid crystal display device includes: a liquid crystal layer between first and second display panels. Then first display panel includes:gate and data lines on a first substrate; a thin film transistor connected to the gate and data lines and exposed at a single contact hole; a color filter on the thin film transistor; a first insulation layer covering the color filter and in which is defined a first contact hole exposing the thin film transistor at the single contact hole; common and pixel electrodes on the first insulation layer and overlapping each other; and a second insulation layer between the pixel and common electrodes and in which is defined a second contact hole exposing the thin film transistor at the single contact hole. Shapes of the first and second contact holes correspond to each other to define the single contact hole at which the thin film transistor is exposed.

1. A liquid crystal display device comprising:
a first display panel and a second display panel facing each other, and a liquid crystal layer between the first and second display panels facing each other; the first display panel comprising:
a first substrate;a gate line and a data line on the first substrate;a thin film transistor connected to the gate line and the data line, a terminal of the thin film transistor exposed at a single contact hole;a color filter on the thin film transistor;a first insulation layer covering the color filter to dispose the color filter between the first insulation layer and the thin film transistor, the first insulation layer including defined therein a first contact hole which exposes the terminal of the thin film transistor at the single contact hole;a common electrode on the first insulation layer covering the color filter;a pixel electrode on the first insulation layer covering the color filter, the pixel electrode overlapping the common electrode; anda second insulation layer between the pixel electrode and the common electrode, the second insulation layer including defined therein a second contact hole which exposes the terminal of the thin film transistor at the single contact hole,wherein a shape of the first contact hole corresponds to a shape of the second contact hole to define the single contact hole at which the terminal of the thin film transistor is exposed.
