Liquid crystal display

Abstract

Each picture element includes first and second sub-picture elements, each of which includes a liquid crystal capacitor and at least one storage capacitor. After a display voltage representing a certain grayscale level has been applied to the respective sub-picture element electrodes of the first and second sub-picture elements, a voltage difference ΔVα is produced between voltages to be applied to the respective liquid crystal capacitors of the first and second sub-picture elements by way of their associated storage capacitor(s). By setting the voltage difference ΔVα value of the blue and / or cyan picture element(s) to be smaller than that of the other color picture elements, shift toward the yellow range at an oblique viewing angle can be minimized.

Description

TECHNICAL FIELD[0001]The present invention relates to a liquid crystal display device and more particularly relates to a liquid crystal display device with an excellent viewing angle characteristic.BACKGROUND ART[0002]Recently, liquid crystal displays (LCDs) have become immensely popular as a big monitor screen for a TV receiver (which will be simply referred to herein as a “TV”).[0003]Those LCDs for use as a big monitor screen for a TV include a so-called “VA mode LCD” that uses a vertical alignment liquid crystal layer (see Patent Document No. 1, for example).[0004]A conventional VA mode LCD has different gamma curves, representing a grayscale-luminance characteristic, when viewed from a frontal viewing angle (i.e., when viewed along a normal to the monitor screen) and when viewed from an oblique viewing angle (i.e., when the polar angle is greater than zero degrees). And as the transmittance at an oblique viewing angle becomes higher than at the frontal viewing angle, the image m...

Benefits of technology

[0030]The present invention provides a liquid crystal display device that can minimize such a loss of the color balance (particularly, a shift toward the yellow range) at an oblique viewing angle and that can be manufactured at a high production yield. The present invention also provides a liquid crystal display device with a novel structure that contributes greatly to achieving such an object.

Problems solved by technology

And as the transmittance at an oblique viewing angle becomes higher than at the frontal viewing angle, the image may look whitish or excessively bright (which is sometimes called a “whitening phenomenon”) at the oblique viewing angle.
