Embodiment Construction

[0025] Embodiments of the invention will now be described in detail, some examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used in the drawings to refer to the same or like parts.

[0026] Hereinafter, the LCD device of the present invention will be described with reference to the accompanying drawings. The LCD device of the present invention includes a reflective region on the lower substrate and a dummy filter on the upper substrate, wherein the dummy filter on the upper substrate is positionally opposed to the reflective region of the lower substrate. At this time, the reflective area reflects incident light provided from the outside of the liquid crystal panel, and the dummy filter transmits light having the same color as that of the housing.

Abstract

The present invention discloses a liquid crystal display device capable of displaying a predetermined color by reflecting externally provided light in a non-driving mode of a liquid crystal panel. The liquid crystal display device includes a lower substrate, an upper substrate, and a case covering the lower substrate and the upper substrate. The lower substrate includes a plurality of pixel areas and a plurality of reflective areas reflecting incident light provided from outside, wherein the plurality of pixel areas are defined by gate lines and data lines intersecting each other at right angles, and a reflective area is formed every predetermined number of pixel areas; the upper The substrate includes a red filter that transmits red light, a green filter that transmits green light, a blue filter that transmits blue light, and a dummy filter that transmits light of a predetermined color. The dummy filter is opposite in position to the reflective area.

Description

[0001] This application claims priority from Korean Patent Application 2009-0128202 filed December 21, 2009, which is hereby incorporated by reference in its entirety as if fully set forth herein. technical field [0002] The invention discloses a liquid crystal display (LCD) device, in particular, an LCD device capable of displaying a predetermined color by reflecting external light in a non-driving mode of a liquid crystal panel. Although the present invention is applicable to a wide range of applications, it is particularly suitable for making the liquid crystal panel display the same color as the housing in the non-driving mode of the liquid crystal panel. Background technique [0003] In general, an active matrix type LCD device displays images by controlling light transmittance of liquid crystals through thin film transistors (hereinafter referred to as "TFT"). Due to the advantages of low power consumption, slim shape, and light weight, LCD devices are widely used in ...
