Abstract
A color filter layer includes a first region and a second region, wherein the number of times that light used for display is transmitted through the color filter layer is different between the first region and the second region.
Claims8
A transflective liquid crystal display device for displaying an image and including a plurality of pixels, the liquid crystal display device comprising:
- a first substrate;
- a second substrate;
- a liquid crystal layer provided between at least the first substrate and the second substrate;
- a pixel region including a reflection region having light-reflectivity and a transmission region having light-transmissivity, wherein reflected light from the reflection region and transmitted light from the transmission region are each utilized in displaying the image;
- wherein one of the substrates supports a color filter structure, the color filter structure including a color filter region and a transmissive non-color filter region, wherein at least portions of both the color filter region and the transmissive non-color filter region are provided in the reflection region of at least one pixel region;
- wherein a transmissive electrode is provided in at least the transmission region, and wherein the transmission electrode is in electrical communication with a transistor;
- wherein a reflective electrode in the reflection region is in electrical communication with the transistor;
- and
- wherein the transmissive non-color filter region is substantially stripe-shaped and is provided between two spaced apart color filters of the same color in a given color filter region, and wherein each of the two spaced apart color filters overlaps a boundary of the pixel region.
