摘要： The present invention provides a low-cost transflective liquid crystal display exhibiting high color reproducibility in a transmissive display and excellent characteristics (color reproducibility and brightness) in a reflective display. Also, the present invention provides a color filter for a bright transflective liquid crystal display.The transflective liquid crystal display includes a pair of substrates disposed opposite to each other with a liquid crystal layer held therebetween, a reflection means using ambient light as a light source, and a backlight source. The transflective liquid crystal display further includes a color filter having a transmissive region and a reflective region which are provided in each picture element of the color filter and which have colored layers comprising a single material, and a three-peak type LED backlight source.

摘要： The present invention provides a color filter comprising a transmission area and reflection area in which at least one color pixel of red, green and blue pixels is formed of the same material, wherein a transparent area having no color layer is formed in a part of the reflection area, at least one sub-area is formed in the transparent area, and the size of the sub-area is 20 μm or more and 2,000 μm or less. The present invention also provides a liquid crystal display for both transmission display and reflection display with a cheap manufacturing cost, wherein the difference of chromaticity between the transmission display and reflection display is small, and the surface of the transmission area and reflection area have small step heights.

摘要： Disclosed is a method for fabricating a color filter for a transflective liquid crystal display device inexpensively in which desired color purities, brightnesses, and color tones are obtained for reflective display and transmissive display. A color filter for a liquid crystal display device includes pixels of a plurality of colors, each pixel of at least one color including a transmissive area and a reflective area. The pixel of at least one color includes a plurality of laminated color layers. The uppermost color layer in the pixel including the plurality of laminated color layers is composed of a photosensitive color resist. In the reflective area of the pixel including the plurality of laminated color layers, a transparent resin layer is disposed between a substrate and the color layer portion.
