Abstract

An electro-optical device includes first and second signal lines that extend in directions for intersecting each other on a component substrate, a pixel area in which a pixel electrode is disposed in correspondence with an intersection of the first and second signal lines, a signal output circuit that is disposed outside the pixel area and outputs a driving signal to the first signal line, and a connection wiring that connects the signal output circuit and the first signal line together. An outer peripheral edge of the pixel area has a curved portion or a bent portion in a portion facing the signal output circuit, and the signal output circuit includes a plurality of circuit blocks, and the circuit blocks are arranged along the curved portion or the bent portion of the portion facing the signal output circuit with deviated between adjacent circuit blocks in the direction of extension of the first signal line and/or the direction of extension of the second signal line.

a plurality of scanning lines and a plurality of data lines that extend in directions for intersecting each other on a component substrate;
a pixel area in which a pixel electrode is disposed in correspondence with an intersection of the scanning lines and the data lines;
a pair of scanning line driving circuits that are both disposed outside the pixel area and that output a driving signal to the scanning lines, each scanning line driving circuit having first and second ends;
a connection wiring that connects the scanning line driving circuits and the scanning lines together;
a data line driving circuit that is disposed outside the pixel area where the respective first ends of the scanning line driving circuits are located, and outputs a driving signal to the data lines; and
a data-line connecting wiring that connects the data line driving circuit and the data lines,
wherein an outer peripheral edge of the pixel area has a curved portion or a bent portion in portions facing the scanning line driving circuits,
wherein a first part of each of the scanning line driving circuits is formed along the curved portion or the bent portion of the outer peripheral edge of the pixel area,
wherein a distance between a second part of each of the scanning line driving circuits and the outer peripheral edge of the pixel area gradually increases toward the first end of the respective scanning line driving circuits, and
wherein the data-line connecting wiring is disposed in a space that is surrounded by the outer peripheral edge of the pixel area, the data line driving circuit, and the second parts of the scanning line driving circuits.

2. The electro-optical device according to claim 1 ,
wherein the component substrate has an outer peripheral edge approximately disposed along the outer peripheral edge of the pixel area.

3. The electro-optical device according to claim 1 ,
wherein a two-dimensional shape of the pixel area is a circle or is formed by combining curves and straight lines.

4. The electro-optical device according to claim 3 ,
wherein the two-dimensional shape of the component substrate is a circle, triangle, or polygon having five or more vertexes or is formed by combining curves and straight lines.

5. The electro-optical device according to claim 3 ,
