Abstract

A region for mounting components such as an IC chip is sufficiently ensured on a glass substrate with which a liquid crystal panel is configured, without reducing the number of panel pieces to be taken from a large panel. A liquid crystal panel is composed of a first glass substrate (10) and a second glass substrate (20) which face each other with a liquid crystal therebetween. The first glass substrate (10) and the second glass substrate (20) are formed in substantially the same size in plan view and bonded together in a state in which these substrates are shifted from each other by a predetermined distance in the direction of the longer side or in the direction of the shorter side. Regions to become a frame (frame regions) are provided on both the first glass substrate (10) and the second glass substrate (20), and pads (60) are provided on both of these frame regions.

Claims

1. A liquid crystal panel, comprising:

a first substrate having a first wiring surface on which electrical wiring is formed; and

a second substrate having a second wiring surface on which electrical wiring is formed, said first substrate and said second substrate being bonded with each other such that a portion of a region on said first wiring surface and a portion of a region on said second wiring surface face each other,

wherein said second wiring surface is formed in substantially the same size as said first wiring surface, and

wherein said first wiring surface and said second wiring surface face each other with a liquid crystal therebetween in a state in which these wiring surfaces are shifted from each other by a predetermined distance in the direction of a longer side or in the direction of a shorter side.

2. The liquid crystal panel according to claim 1, wherein one or more electrodes are provided in both a first frame region, which is, in the region on said first wiring surface, a region that does not face said second wiring surface, and a second frame region, which is, in the region on said second wiring surface, a region that does not face said first wiring surface.

3. The liquid crystal panel according to claim 2, wherein said first wiring surface and said second wiring surface are formed such that a wiring resistance in said second wiring surface is greater than a wiring resistance in said first wiring surface, and

wherein a circuit for driving said liquid crystal is formed in said first frame region.

4. The liquid crystal panel according to claim 2, wherein at least one of the electrodes provided in said second frame region is connected to a third substrate having electrical wiring.

5. The liquid crystal panel according to claim 4, wherein a light-emitting diode is provided in said second frame region, and said light-emitting diode and said third substrate are electrically connected via the electrical wiring formed on said second wiring surface.

6. The liquid crystal panel according to claim 4, wherein a sensor chip is provided in said second frame region, and said sensor chip and said third substrate are electrically connected via the electrical wiring formed on said second wiring surface.

7. The liquid crystal panel according to claim 2, wherein at least one of the electrodes provided in said first frame region is connected to a flexible printed board.

8. The liquid crystal panel according to claim 2, wherein at least one of the electrodes provided in said second frame region is connected to an integrated circuit chip.

9. The liquid crystal panel according to claim 2, wherein at least one of the electrodes provided in said second frame region is connected to a flexible printed board.

10. The liquid crystal panel according to claim 2, wherein at least one of the electrodes provided in said first frame region is connected directly or via a flexible printed board to a fourth substrate which is a main board for communication functions, and

wherein at least one of the electrodes provided in said second frame region is connected directly or via a flexible printed board to a fifth substrate which is a sub-board on which a component for communication functions is mounted.
