Embodiment Construction

[0042] The present invention is described more fully hereinafter with reference to the accompanying drawings showing preferred embodiments of the invention.

[0043] Layer thicknesses and areas in the figures are exaggerated for better clarity. The same reference numerals designate the same elements. It will be understood that when an element such as a layer, region or substrate is said to be "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is said to be "directly on" another element, there are no intervening elements.

[0044] An LCD according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0045] FIG. 1 is a cross-sectional view of an LCD according to an embodiment of the present invention. 2 to 5 show the arrangement of color filters of an LCD according to an embodiment of the present invention.

[0046]As shown ...

Abstract

This liquid crystal display includes a liquid crystal display panel having a red filter having red pixels, a green filter having green pixels, a blue filter having blue pixels and white pixels W; and a back light unit disposed in one side of the panel. Light emitted from the back light unit has x-color coordinates ranging from 0.31 to 0.34, and y-color coordinates from 0.32 to 0.35.

Description

[0001] This application is a divisional application of the No. 03127473.0 invention patent application with the filing date of May 4, 2003, entitled "Liquid Crystal Display and Its Color Filter Array Board". technical field [0002] The invention relates to a liquid crystal display and a used display panel, in particular to a four-color liquid crystal display. Background technique [0003] In general, a liquid crystal display (LCD) includes: a liquid crystal panel assembly (liquid crystal panel assembly), which includes two panels provided with two types of field generating electrodes such as a pixel electrode and a common electrode; A liquid crystal layer with anisotropic dielectric properties between them. A change in the voltage difference between the field generating electrodes, that is, a change in the intensity of an electric field generated by the electrodes, causes a change in light transmittance through the LCD, and thus, controlling the voltage difference between t...
