Display device and electronic device

Abstract

The invention provides a display device and electronic device. The display device comprises a first sub-pixel area, a second sun-pixel area and a third sub-pixel area. The first sub-pixel area comprises a first main penetrating wavelength, the second sub-pixel area comprises a second main penetrating wavelength, and the third sub-pixel area comprises a third main penetrating wavelength. A first electrode width of a first finger-fork electrode in a first sub-pixel area and a first electrode interval of the first finger-fork electrode in the first pixel area possess a first specific value, a second electrode width of a second finger-fork electrode in a second sub-pixel area and a second electrode interval of a second finger-fork electrode in a second sub-pixel area possess a second specific value, and a third electrode width of a third finger-fork electrode in a third sub-pixel area and a third electrode interval third finger-fork electrode in a third sub-pixel area possess a third specific value. The first main penetrating wavelength is larger than the second main penetrating wavelength, and the second main penetrating wavelength is larger than the third main penetrating wavelength, the first specific value, the second specific value and the third specific value are almost the same, the first electrode interval is smaller than the second electrode interval, and the second electrode interval is smaller than the third electrode interval.

Description

technical field [0001] The invention relates to a display device, in particular to a low-dispersion blue-phase liquid crystal display. Background technique [0002] The blue phase liquid crystal has the advantages of short response time and no need for alignment film. Moreover, the blue-phase liquid crystal has optically isotropic properties without an external electric field, and thus has an excellent dark state. [0003] For traditional liquid crystals, the dispersion relationship of liquid crystal birefringence can be described by the extended Cauchy equation (Equation (1)).

AI Technical Summary

Problems solved by technology

like figure 1 As shown, it is known that the voltage-to-transmittance curves of different sub-pixels of a blue-phase liquid crystal display have poor coincidence, the dispersion is serious, and the color shift effect is relatively high under different viewing angles.
