Title:
LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/046931
Kind Code:
A1
Abstract:
Provided is a liquid crystal display device capable of sufficiently reducing the delay when displaying pixels by minimizing the parasitic capacity of a data line as much as possible. In an IPS liquid crystal display device, a first electrode 34 connected to a data line 32, and a second electrode 35 connected to a gate line 31 and common wiring 33 through a TFT 36 are arranged in a portion corresponding to each pixel in an active matrix circuit. An electric field is generated between the first electrode 34 and the second electrode 35, to thereby drive the liquid crystal. Since the TFT is not connected between the data line 32 and the first electrode 34, the capacity between the data line 32 and the first electrode 34 is small; no shield is required to prevent the generation of unwanted electric fields between the data line 32 and the electrode; therefore, no capacity is generated between the data line 32 and the shield. Thereby, it is possible to minimize the parasitic capacity of the data line 32, decrease the delay of a signal passing through the data line 32, and sufficiently reduce the delay when displaying pixels.
