Abstract: PROBLEM TO BE SOLVED: To easily decrease occurrence of brightness unevenness and flickering without problems in productivity and costs.
SOLUTION: An output waveform of a potential outputted from a switching part 16 of a gate driver IC 7 to scanning lines G is set as a waveform including a 1st waveform which has a potential to bring a switching element into ON state as the amplitude, and a 2nd waveform which follows the 1st waveform, and also oscillates within a period shorter than the 1st waveform with an amplitude smaller than the 1st waveform. Thus, the falling waveforms of the scanning signals to be supplied to the switching elements via the scanning lines G are made to beforehand decline, to relax the unevenness of the declinations of the falling waveforms of the scanning signals to be supplied to each switching element, and thereby suppress occurrence of brightness unevenness and flickering in a screen.

Abstract: PURPOSE: To eliminate signal delay of a common electrode in a liquid crystal display device of an active matrix system. CONSTITUTION: Columns 78 of a color filter 32 are provided to specify a cell gap between an array board 12 with a storage capacity line 28 and an opposed board 72 with the color filter 32, and a common electrode 30 that covers the columns 78 of the color filter 32 is electrically connected to the storage capacity line 28 on the array board 12 to feed electric potential from the storage capacity line 28 to the common electrode 30. A transfer dotting process can thereby be eliminated, and signal delay of the common electrode 30 can be eliminated. In addition, the cell gap does not differ depending on a place by fixing the columns 78 of the color filter 32, which results in improving image quality besides keeping the uniformity of an image plane. Cost can be also reduced by dispensing with the transfer dotting process and a spacer dispersing process.
