1-21. (canceled)
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 at least one 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;
- wherein a transmissive electrode is provided in at least the transmission region, and wherein the transmissive electrode is in electrical communication with a transistor corresponding to the pixel region;
- wherein a reflective layer is provided in the reflection region;
- and
- wherein the transmissive non-color filter region is substantially rectangular shaped.
