Abstract

A display region E that includes an element isolation region 88 having a display region trench density D 1 , and in which a pixel circuit 110 including a transistor is arranged; a drive circuit region 105 that includes a region in which a drive circuit element isolation portion having a drive circuit region trench density D 2 is provided, and in which drive circuits 101 and 102 that supply signals for driving the pixel circuit 110 are arranged; and a peripheral region 106 that includes region in which a peripheral element isolation portion having a peripheral region trench density D 3 is provided, and is arranged at least between the display region E and the drive circuit region 105 . The display region trench density D 1 is different from the drive circuit region trench density D 2 , and the display region trench density D 1 is equal to the peripheral region trench density D 3.

First claim

What is claimed is:

1. An electro-optical device comprising:
a first region that includes a first trench element isolation region and a pixel circuit including a transistor, the pixel circuit being isolated by the first trench element isolation region, the first trench element isolation region having a first trench density defined as a ratio of an area of the first trench element isolation region relative to an area of the first region;
a second region that includes a second trench element isolation region and a drive circuit that supplies a signal for driving the pixel circuit, the drive circuit being isolated by the second trench element isolation region, the second trench element isolation region having a second trench density defined as a ratio of an area of the second trench element isolation region relative to an area of the second region; and
a third region that includes a third trench element isolation region and is arranged at least between the first region and the second region, the third trench element isolation region having a third trench density defined as a ratio of an area of the third trench element isolation region relative to an area of the third region,
wherein the first trench density is different from the second trench density, and the first trench density is equal to the third trench density.

2. The electro-optical device according to claim 1 , wherein the third region surrounds the first region.

3. An electronic apparatus comprising the electro-optical device according to claim 2 .

4. The electro-optical device according to claim 1 , wherein the third region surrounds the second region.

5. An electronic apparatus comprising the electro-optical device according to claim 4 .

6. An electronic apparatus comprising the electro-optical device according to claim 1 .
