Embodiment Construction

[0038] Exemplary embodiments of the present invention will be described in detail below with reference to the examples in the accompanying drawings.

[0039] In general, in an IPS mode liquid crystal display device, light is transmitted through a region between a common electrode and a pixel electrode. According to the number of common electrodes and pixel electrodes, the light transmission area changes, and the light transmission generally appears as a block. For example, in the IPS mode liquid crystal display device shown in FIGS. 2A and 2B, three common electrodes and two pixel electrodes are formed, and there are four light-transmitting regions. Here, an IPS mode liquid crystal display device (4 pieces of liquid crystal display device) having four light-transmitting regions is described, but this is not to limit the present invention to a liquid crystal display device of a specific structure, but for convenience. The IPS mode liquid crystal display device according to the...

Abstract

An in-plane switching mode liquid crystal display device includes a substrate; at least two gate lines disposed on the substrate; at least two data lines disposed on the substrate crossing the gate lines to define a pixel region; a driving device disposed in the pixel region; a plurality of first electrodes disposed in the pixel region; and a plurality of second electrodes disposed in the pixel region parallel with the first electrodes. At least one first electrode is overlapped with at least one second electrode. Further, each one of the first electrodes and a corresponding one of second electrodes defining an electric field in a direction parallel to a surface of the substrate.

Description

technical field [0001] The present invention relates to liquid crystal display devices, in particular to in-plane switching mode liquid crystal display devices with improved aperture ratio. Background technique [0002] Recently, with the development of various portable electronic devices, such as mobile phones, PDAs, and notebook computers, demands for flat panel display devices having light weight, small size, and adaptability have gradually increased. Liquid crystal displays (LCDs), plasma display panels (PDPs), field emission displays (FEDs), vacuum fluorescent displays (VFDs), and the like have been actively studied as flat panel display devices. Among these display devices, LCDs are currently attracting the most attention in terms of mass production. [0003] LCDs have various display modes according to the arrangement of liquid crystal molecules. Among them, the TN (Twisted Nematic) mode is mainly used at present due to the ease of black-and-white display, fast resp...
