Liquid crystal display device
View Patent ↗In order to make a boundary inconspicuous, which is located between an image area which displays an image by translucent pixels and a dummy area which always displays a white color by reflection pixels, a size ratio of transparent areas in color filters of the reflection pixels with respect to reflection areas therein is made larger than a size ratio of transparent areas in color filters of the translucent pixels with respect to reflection areas therein. In such a way, brightness of the display is balanced by adjusting quantities of transmission light through the transparent areas of the reflection pixels with respect to quantities of reflection light generated unexpectedly on transmission areas of the translucent pixels. Then, degrees of whiteness in the translucent pixels and the reflection pixels are approximated to each other.
1. A liquid crystal display device, comprising:
an image area in which a plurality of transflective pixels having reflection areas and transmission areas are arrayed;
a reflection display area in which a plurality of reflection pixels having only reflection areas are arrayed, the reflection area being disposed on a periphery of the image area; and
color filters in which clear areas are provided for each color in the respective reflection areas of the transflective pixels and the reflection pixels, wherein,
with regard to color filters of at least the same one color, a size ratio of the clear areas in the reflection pixels with respect to the reflection areas therein is larger than a size ratio of the clear areas in the transflective pixels with respect to the reflection areas therein,
a size of the reflection areas of the reflection pixels is equal to a size of the reflection areas of the transflective pixels, and
a size of the clear areas provided in the color filters of the reflection pixels is larger than a size of the clear areas provided in the color filters of the transflective pixels.

wherein,
with regard to color filters of at least the same one color, a size ratio of the clear areas in the reflection pixels with respect to the reflection areas therein is larger than a size ratio of the clear areas in the transflective pixels with respect to the reflection areas therein,
the color filters are the three colors being red, green, and blue,
a size of the reflection areas of the reflection pixels is larger than a size of the reflection areas of the transflective pixels,
in the blue color filter, the size ratio of the clear areas provided in the reflection pixels with respect to the reflection areas provided therein is larger than the size ratio of the clear areas provided in the transflective pixels with respect to the reflection areas provided therein, and
in each of the red and green color filters, the size ratio of the clear areas provided in the reflection pixels with respect to the reflection areas provided therein is smaller than the size ratio of the clear areas provided in the transflective pixels with respect to the reflection areas provided therein.
