Abstract
A display device includes a first substrate provided with first picture electrodes having reflecting parts a second transparent substrate provided with transparent second picture electrodes, with pixels at areas of overlapping parts of the first and second picture electrodes, an electro-optic material between the first and second substrates and a color filter present on the first substrate, wherein viewed transversely to the first substrate, within a pixel, the color filter partly covers the reflecting part of the first picture electrode. By such a configuration, light from an uncovered part of a picture electrode is mixed with light from the part of the electrode that is covered by the color filter to increase the intensity of the display.

A display device, comprising:
- a first substrate having a first picture electrode disposed thereon, said first picture electrode including a transparent layer and a reflective layer disposed thereon;
- a second transparent substrate having a transparent second picture electrode disposed thereon, with a pixel at an area where the first and second picture electrodes overlap;
- an electro-optic material between the first and second substrates;
- and
- a color filter disposed on the first picture electrode, wherein viewed transversely to the first substrate, within the pixel, the color filter only partly covers the first picture electrode.
