Abstract: There is provided a high-definition liquid crystal display device that can prevent flicker due to a reduction in the pixel potential in a low-frequency drive of about 10 Hz to reduce power consumption. The pixel has a TFT formed of Poly-Si as a switching element. In the pixel, a capacitance insulating film is formed on a planar first electrode on which a comb-shaped second electrode is formed. When the film thickness of the insulating film is d and the dielectric constant at 10 Hz frequency is ∈, it is given that ∈d≧5×10−6 m at 10 Hz frequency. The capacitance insulating film does not have a hysteresis characteristic. The refractive index of the capacitance insulating film with respect to a light of a wavelength of 632.8 nm is 1.7 to 2.0.

The second area is smaller than the first area in a first direction, and the second area is adjacent to the first area in a second direction orthogonal to the first direction. A non-display area is adjacent to the second area in the first direction and adjacent to the first area in the second direction. A plurality of pixel circuits is arranged in the display area in the first direction and the second direction, avoiding the non-display area. A plurality of first control lines and second control lines are grouped into control line assemblies arranged such that control line assemblies of different types belonging to each of the plurality of groups are adjacent to each other, in order to simplify load adjustment.
