Display device
First Claim
1. A display device, comprising:
- a scanning signal line driving circuit for driving scanning signal lines; and
a data signal line driving circuit for driving data signal lines intersecting the scanning signal lines, at least one of the scanning signal line driving circuit and the data signal line driving circuit being supplied with at least first and second signals, the first signal being supplied in parallel to other circuit than the driving circuit supplied with the first and second signals, the other circuit being one of the scanning signal line driving circuit, the data signal line driving circuit, and a pre-charging circuit for carrying out pre-charging of the data signal lines, the display device further comprising wiring load adjustment section for equalizing wiring load of the second signal which is supplied to the driving circuit, and wiring load of the first signal which is supplied in parallel to the driving circuit and the other circuit.

Abstract
In a structure in which a plurality of signals related to each other are supplied to a driving circuit in such a manner that at least one of the signals is supplied also to the other circuit, the present invention prevents change of phase relation between the plural signals due to difference in wiring load, without directly processing the signals with higher power consumption. The first and second clock signals SCK1 and SCK2 are supplied to the first data signal line driving circuit SD1, while the first clock signal SCK1 is also supplied to the second data signal line driving circuit SD2 in parallel. The wirings 1 and 2 for the respective signals are adjusted to have equal wiring load with a dummy wiring 2 provided in the wiring 2, for solving uneven wiring load caused by difference of leading manner, the dummy wiring 2 constituting an additional capacitor section 7, together with a liquid crystal layer and a counter electrode.
