Optical modulation apparatus
View Patent ↗An optical modulation apparatus includes a light irradiation section, a plurality of rectangular pixel electrodes arranged on two lines separately at regular intervals in such a manner that short sides of adjacent pixel electrodes face each other and drive an optical modulation substance; a driver element is disposed below the pixel electrode and drives the pixel electrode; and a pixel electrode connection that electrically connects the pixel electrode and the driver element, wherein the pixel electrode connection is disposed outside the light irradiation section.
1. An optical modulation apparatus comprising:
a plurality of rectangular pixel electrodes that are arranged on two lines separately at regular intervals in such a manner that short sides of adjacent pixel electrodes face each other and that drive an optical modulation substance;
a driver element that is disposed below the pixel electrode and that drives the pixel electrode; and
a pixel electrode connection that electrically connects the pixel electrode and the driver element,
wherein the pixel electrode has a light irradiation section, wherein the light irradiation section is the section of the pixel electrode that is irradiated by light,
wherein the pixel electrode connection is disposed outside the light irradiation section, and
wherein the light irradiation section is common to the plurality of rectangular pixel electrodes.
2. The optical modulation apparatus as defined in claim 1 , wherein the pixel electrode connection is disposed along the outer circumference of the light irradiation section.
3. The optical modulation apparatus as defined in claim 2 , wherein a pixel electrode connection disposed close to the outer circumference of the light irradiation section and a pixel electrode connection disposed separately from the outer circumference of the light irradiation section are arranged in alternate shifts along the outer circumference of the light irradiation section.
4. The optical modulation apparatus as defined in claim 1 , wherein the pixel electrode connections in the pixel electrodes disposed adjacently to each other in a long side direction are not disposed adjacently to each other.
5. The optical modulation apparatus as defined in claim 1 , wherein two pixel electrode connections are disposed in each pixel electrode.
6. The optical modulation apparatus as defined in claim 1 , wherein the pixel electrode connection is disposed close to a short side which is opposite to short sides facing each other in the pixel electrodes.
7. The optical modulation apparatus as defined in claim 2 , wherein two pixel electrode connections are disposed in each pixel electrode.
8. The optical modulation apparatus as defined in claim 3 , wherein two pixel electrode connections are disposed in each pixel electrode.
9. The optical modulation apparatus as defined in claim 4 , wherein two pixel electrode connections are disposed in each pixel electrode.
