Abstract

The invention provides an electrooptic device and an electronic device in which a region that does not directly contribute to the display can be narrowed by improving the layout of peripheral circuits. In a TFT array substrate of a liquid crystal device, unit circuits that form shift register circuits are formed in unit-circuit forming regions spaced from each other in the X-direction, and the X-direction pitch of the circuit units is shorter than the X-direction pitch of pixel rows. Consequently, a wide free region in which the unit circuits 101 e are not formed can be formed between the unit-circuit forming regions, and identification marks can be formed in the region.

Claims (16)

1. An electrooptic device comprising, on a substrate:

an image display region in which a plurality of pixels are arranged at a predetermined pitch in X- and Y-directions intersecting on said substrate;

a peripheral circuit disposed in a region adjacent in the Y-direction to said image display region; and

a plurality of unit circuits corresponding to a plurality of pixel rows arranged in the X-direction that are arranged at a predetermined pitch in the X-direction at least in a portion of said peripheral circuit, and said plurality of unit circuits are formed offset in the X-direction from regions extending in the Y-direction from said corresponding pixel rows, so that a free region in which said unit circuits are not formed is formed in a portion of said region adjacent in the Y-direction to said image display region, said portion being adjacent in the X-direction to said portion in which said unit circuits are formed, said free region being formed on both sides or one side adjacent in the X-direction to said portion in which said unit circuits are formed in said peripheral circuit by setting an X-direction pitch of said unit circuits to be shorter than an X-direction pitch of said pixel rows.

2. An electrooptic device according to claim 1 , said free region being formed between a plurality of unit-forming regions spaced from each other in the X-direction in said peripheral circuit by forming said unit circuits in said unit-circuit forming regions.

3. An electrooptic device according to claim 1 , an identification mark having various data recorded therein being disposed in said free region.

4. An electrooptic device according to claim 1 , said substrate having a conductive electrode that is electrically connected to an electrode on a counter substrate opposing said substrate through a conductive material that is held between said substrates, and said conductive electrode being formed in said free region.

5. An electrooptic device according to claim 1 , said substrate having a conductive electrode that is electrically connected to an electrode on a counter substrate opposing said substrate through a conductive material that is held between said substrates, and said conductive electrode and an identification mark having various data recorded therein are formed in said free region.

6. An electrooptic device according to claim 1 , said plurality of pixels including pixel electrodes and pixel-switching thin-film transistors, respectively, and said peripheral circuit being a data-line driving circuit in which said unit circuits are formed in a one-to-one correspondence with data lines electrically connected to sources of pixel-switching thin-film transistors.

7. An electrooptic device according to claim 1 , said plurality of pixels including pixel electrodes and pixel-switching thin-film transistors, respectively, and said peripheral circuit being a scanning-line driving circuit in which said unit circuits are formed in a one-to-one correspondence with scanning lines electrically connected to gates of pixel-switching thin-film transistors.

8. An electrooptic device according to claim 1 , said substrate holding liquid crystal as an electrooptic substance.

9. An electronic device having the electrooptic device according to claim 1 .

10. An electrooptic device comprising, on a substrate:

an image display region in which a plurality of pixels are arranged at a predetermined pitch in X- and Y-directions intersecting on said substrate;

a peripheral circuit disposed in a region adjacent in the Y-direction to said image display region; and

a plurality of unit circuits corresponding to a plurality of pixel rows arranged in the X-direction that are arranged at a predetermined pitch in the X-direction at least in a portion of said peripheral circuit, and said plurality of unit circuits are formed offset in the X-direction from regions extending in the Y-direction from said corresponding pixel rows, so that a free region in which said unit circuits are not formed is formed in a portion of said region adjacent in the Y-direction to said image display region, said portion being adjacent in the X-direction to said portion in which said unit circuits are formed, said free region being formed between a plurality of unit-forming regions spaced from each other in the X-direction in said peripheral circuit by setting an X-direction pitch of said unit circuits to be shorter than an X-direction pitch of said pixel rows and by forming said unit circuits in said unit-circuit forming regions.
