Display device and method of manufacturing the same
View Patent ↗A display device includes an upper substrate and a lower substrate. Black matrixes are formed upon the upper substrate and color filters are formed between the black matrixes. Microshutter electrodes are formed upon the lower substrate and are configured to open and close. The display device also includes fixed electrodes formed in a vertical direction between the upper substrate and the lower substrate.
1. A display device comprising:
an upper substrate;
a lower substrate;
microshutter electrodes formed upon the lower substrate, the microshutter electrodes configured to open and close;
fixed electrodes formed in a vertical direction between the upper substrate and the lower substrate;
black matrixes formed upon the upper substrate; and
color filters formed between the black matrixes,
wherein the microshutter electrodes are opened and closed in a vertical direction, and
wherein the fixed electrodes support the upper substrate and the lower substrate.
2. The display device of claim 1 , wherein the fixed electrodes are formed in a region that is covered with the black matrixes.
3. The display device of claim 1 , wherein two microshutter electrodes are symmetrically formed in one pixel and have a curved shape.
4. The display device of claim 3 , wherein the two microshutter electrodes are arranged in a vertical direction to allow transmission of light from a light source to the upper substrate.
5. The display device of claim 3 , wherein the two microshutter electrodes are in contact with each other to block the transmission of light from the light source to the upper substrate.
6. The display device of claim 3 , wherein the two microshutter electrodes overlap each other to block the transmission of light from the light source to the upper substrate.
7. The display device of claim 3 , wherein each of the microshutter electrodes extends upward from the lower substrate and curves at end portions thereof to face each other.
