There is provided a device capable of switching between a state that displays a high-quality image and a mirror status in which is obtained an easy-to-view reflection image suitable for a person to view his/her own face or figure. An image display portion 1000 that emits image light 3001, reflective polarization selection means 300 that transmits a first linear polarization component emitted from the image display portion 1000 and reflects a second linear polarization component, whose polarization axis is orthogonal to that of the first linear polarization component, a transmission polarization axis variable portion 400 capable of selecting between one of a state that changes the polarization axis of incident linearly polarized light and a state that does not change the polarization axis of incident linearly polarized light, and a polarization selection member 500 which, of the incident light, absorbs the first linear polarization component and transmits the second linear polarization component, whose polarization axis is orthogonal to that of the first linear polarization component, are disposed in this order. In this case, absorbing polarization selection means 208 is disposed at the image display portion 1000, and the first linear polarization is emitted as the image light.

The present invention provides a liquid crystal display device, by which it is possible to improve color reproducibility and contrast by adequately setting a value of Δn·d of each color without changing thickness of liquid crystal layer. A partition wall PT made of resin is prepared between pixels, which comprises color filter columns of CF-R, CF-G and CF-B. Within each of the pixels partitioned by the partition wall, liquid crystals LC(R), LC(G), and LC(B) having different values of Δn are filled In the pixels partitioned by the partition wall. The partition wall PT also fulfills the function as a spacer to maintain cell gap at a predetermined value.

An image display displays image data on an image display part constructed by a display pixel array. In an image display in which image data input means for inputting image data so that the display pixel array has two neighboring areas having different frame rates (>0) is provided or image data is displayed on an image display part constructed by a display pixel array, there is provided image data input means which can input at least one moving image data and at least one still image data into the image display part at different frame rates (>0). A high precision image display can be realized hardly changing a display pixel rewriting speed. A moving image signal output circuit and a still image signal output circuit output image data to the display pixel array, and they are provided as circuit configurations independent of each other.

A display device including a plurality of blocks of pixels each of which includes a red subpixel, a green subpixel, and a blue subpixel, each of the blocks including pixels in a form of a matrix having N rows and M columns includes a first active element shared among three subpixels of each pixel and a second active element connected to a second active element formed in each subpixel connected to the first active element. Ma gradation voltage lines (Ma is an integer; M≧Ma≧2) respectively of red, green, and blue subpixels in a direction of the column are commonly connected. The display device directly displays a compressed image signal without developing the image signal into a bit map in which each subpixel has gradation information.
