COLOR FILTER AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain a bright color filter for a semitransmissive liquid crystal display device having little difference in chromaticity between a reflective mode and a transmissive mode and to obtain the semitransmissive liquid crystal display device having high color reproducibility in a transmissive display, having excellent characteristics (color reproducibility and brightness) in a reflective display and being low-cost. SOLUTION: The color filter contains transmission regions 7 and reflection regions 6, comprises pixels of at least one color in which the transmission region and the reflection region are composed of an identical color material and the reflection region contains a transparent region and further comprises pixels of at least one color except for the pixels containing the transparent region which have two or more kinds of coloring layers stacked on the transmission region. The semitransmissive liquid crystal display device uses a three wavelength-type LED (light emitting diode) light source as a backlight light source and the color filter containing the pixels of at least one color in which the transmission region and the reflection region are composed of an identical coloring layer and has the transparent region in the reflection region.
