Patent ID: 8665200

Claim:
A display device in which a storage capacitor line is driven with a driving signal, wherein: the driving signal, which is generated in said display device, has an electric potential waveform in which each one (I) frame period is made up of a first period, a second period, a third period, and a fourth period, which are sequential periods in this order and have respective lengths, an electric potential level(s) of the driving signal being set in each of the first, second, third, and fourth periods; the first period starts based on a generation timing of a timing signal which determines a start timing of the one (I) frame period, the driving signal having any one of a first High level and a first Low level during the first period, and the first High level and the first Low level being alternated every frame period; in the second period, the electric potential level alternates between a second High level and a second Low level; during the third period, (i) the driving signal has a third High level when the driving signal has the first High level during the first period of the same frame or (ii) the driving signal has a third Low level when the driving signal has the first Low level during the first period of the same frame; in the fourth period, the electric potential level alternates between a fourth High level and a fourth Low level until a generation timing of the timing signal which determines a start timing of a following one (I) frame period; any adjacent two of the frame periods belong to a first frame and a second frame, respectively; in the first frame, the driving signal has (i) the first Low level during the first period, (ii) the second High level at the beginning and the end of the second period, and (iii) the third Low level during the third period, each of the first Low level and the third Low level being lower in electric potential than the second Low level; and in the second frame, the driving signal has (i) the first High level during the first period, (ii) the second Low level at the beginning and the end of the second period, and (iii) the third High level during the third period, each of the first High level and the third High level being higher in electric potential than the second High level.
