Abstract:
1. An electrooptical panel, comprising a first substrate including a plurality of scanning lines formed thereon, a second substrate that is disposed opposing the first substrate so that a constant gap is maintained therebetween, a sealing portion arranged between the first substrate and the second substrate on the inner surfaces thereof adjacent to and along the peripheral edges thereof, the second substrate having a plurality data lines, switching elements and pixel electrodes, with each of the switching elements and pixel electrode arranged at each intersection of the scanning lines and the data lines, and an electrooptical material disposed in the gap between the first substrate and the second substrate, wherein the electrooptical panel further comprises: a first wiring group arranged adjacent to a first edge of the electrooptical panel wherein the first wiring group includes a first plurality of wirings arranged on the second substrate and adjacent to the first edge of the panel, and a first conductor portion, arranged in the sealing portion, for respectively connecting a plurality of scanning lines, out of the scanning lines, corresponding to the first wiring group, with the first plurality of wirings; a second wiring group arranged adjacent to a second edge of the electrooptical panel that is opposite to the first edge of the electrooptical panel wherein the second wiring group includes a second plurality of wirings arranged on the second substrate adjacent to the second edge of the panel, and a second conductor portion, arranged in the sealing portion, for respectively connecting a plurality of scanning lines, out of the scanning lines, corresponding to the second wiring group, with the second plurality of wirings; and wherein the scanning lines are alternately connected to the first wiring group by K lines and the second wiring group by K lines in a manner such that first K scanning lines are connected to the first wiring group, second K scanning lines are connected to the second wiring group, third K scanning lines are connected to the first wiring group, and so on, and the first plurality of wirings which are connected to the plurality of scanning lines, out of the scanning lines corresponding to the first wiring group, are extended on the first substrate along the first edge of the panel, and the second plurality of wirings which are connected to the plurality of scanning lines, out of the scanning lines corresponding to the second wiring group, extended on the first substrate along the second edge of the panel, the scanning lines being successively selected for each horizontal scanning period so that the selected scanning line is supplied with a selection voltage, and is then supplied with a non-selection voltage, and the polarities of the selection voltage and the non-selection voltage are inverted every K horizontal scanning periods with respect to an intermediate value, between an ON voltage and an OFF voltage, supplied to the data line, and the scanning lines connected to the first wiring group are supplied with the same polarities of the selection voltage and non-selection voltage, and the scanning lines connected to the second wiring group are supplied with the same polarities of the selection voltage and non-selection voltage.
