Title:

COLOR FILTER FOR LIQUID CRYSTAL DISPLAY AND SEMITRANSMISSION LIQUID CRYSTAL DISPLAY

Document Type and Number:

WIPO Patent Application WO/2003/102638

Kind Code:

A1

Abstract:

A semitransmission liquid crystal display having a high color reproducibility in the transmission display mode and excellent characteristics (color reproducibility, luminance) in the reflection display mode and produced at low cost and a color filter for a semitransmission liquid crystal display such that the difference in chromaticity between the reflection display and transmission display is small, and the luminance is high are disclosed. The semitransmission liquid crystal display comprising reflecting means including a pair of opposed substrates with a liquid crystal layer interposed therebetween and a light source using ambient light and a backlight light source is characterized in that a color filter having pixels each including transmission and reflection regions and a coloring layer made of the same material is provided and the backlight light source is a three−wavelength LED backlight.
