Problems solved by technology

However, in this case, signal interference is generated due to the touch wiring, and the transmittance is lowered due to the touch wiring, thereby degrading the image quality of the LCD device and increasing the thickness of the liquid crystal panel, limiting the performance of the LCD device. size reduction
In addition, the manufacturing process of the liquid crystal panel becomes complicated

Embodiment Construction

[0030] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] In an embodiment of the present invention, a part of the touch panel is formed inside the liquid crystal panel, and the other part of the touch panel is formed outside the liquid crystal panel. However, in this case, only some elements of the touch panel are formed inside the liquid crystal panel, and the touch panel is neither completely a built-in type touch panel in which the touch panel is fully installed inside the liquid crystal panel, nor is the touch panel attached to the outside of the liquid crystal panel. mounted touch panel. Since some elements of the touch panel are formed inside the liquid crystal panel and other elements of the touch panel are formed outside the liquid crystal panel, the touch panel has characteristics of a built-in type touch panel and / or an mount type touch panel. In other words, the touch panel according to the ...

Abstract

A liquid crystal display device including a touch panel having a simple structure and minimized thickness is provided. The liquid crystal display (LCD) device according to an embodiment includes a liquid crystal panel and a touch panel structure. The liquid crystal panel includes a thin film transistor (TFT) array substrate, a color filter substrate having a black matrix therein, and a liquid crystal layer disposed between the TFT array substrate and the color filter substrate. The touch panel structure includes at least one touch sensor. Each touch sensor includes a first electrode disposed within the liquid crystal panel, and a second electrode disposed outside the liquid crystal panel.

Description

technical field [0001] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device with a touch panel. Background technique [0002] In recent years, with the development of various portable electronic devices such as mobile phones, PDAs, notebook computers, etc., and large electronic devices, the demand for lighter, thinner, shorter and smaller flat panel display devices has increased. A liquid crystal display (LCD), a plasma panel (PDP), a field emission display (FED), and a vacuum fluorescent display (VFD), which are flat panel display devices, have been actively researched. [0003] Among them, personal computers, portable communication devices, and other personal information processing devices usually use various input devices such as keyboards, mice, digitizers, etc. to interact with users. However, with the development of portable electronic devices, on some portable electronic devices, input devices suc...
