Abstract: The present invention discloses a liquid crystal display panel and a display. The display panel comprises a first substrate and a second substrate opposed to each other, and a liquid crystal layer located between the first substrate and the second substrate. A first common electrode and an insulating layer are sequentially provided on the side of the first substrate toward the second substrate. Multiple first pixel electrodes are provided on the insulating layer. Multiple second common electrodes and multiple second pixel electrodes are provided on the side of the second substrate toward the first substrate. The second common electrodes and the second pixel electrodes are provided at intervals.

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 fanned. 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.
