The present invention provides a liquid crystal display device in which display unevenness is suppressed by preventing degradation of TFT characteristics due to photo-alignment treatment. The liquid crystal display of the present invention includes: a thin-film transistor substrate; and a liquid crystal layer, the thin-film transistor substrate including a thin-film transistor having a channel etch structure and an alignment film, the thin-film transistor including a gate electrode, a gate insulating film, a channel layer containing an oxide semiconductor, and a pair of a source electrode and a drain electrode in the stated order, the alignment film including at least one selected from the group consisting of a cinnamate structure, a chalcone structure, an azobenzene structure, a stilbene structure, a coumarin structure, and a phenyl ester structure.

Ring modulators based on interdigitated junctions may be driven in full or partial standing wave mode and, active regions (providing the modulation) and light-absorptive regions (e.g. providing electrical conduction) are placed in a pattern inside a resonant cavity in order to match the maxima and minima of the optical field, respectively. The pattern may be periodic to match the periodicity of a typical electromagnetic field which is periodic with the wavelength. It may also be aperiodic in the case that the cross-section or materials are engineered along the direction of propagation such that the propagation constant (and thus wavelength, i.e. optical wave “local periodicity”) change along the propagation direction.

The electronic device includes a first housing including a solar battery, a first display device, and a first structure body and a second housing including a second display device, a coil, an electric double-layer capacitor, a signal processing circuit, a charge and discharge control circuit, and a second structure body. The electronic device can be folded so that display surfaces of the first housing and the second housing face each other and the first structure body and the second structure body face each other. The solar battery is provided on a surface of the first housing on the rear side of the first display device. A pixel included in the first display device and a pixel included in the second display device each include a liquid crystal element, a first pixel circuit, a light-emitting element, and a second pixel circuit. The liquid crystal element includes a reflective electrode having an opening and can perform display by reflecting external light. The light-emitting element can perform display by emitting light toward the display surface through the opening.

An example optical polarization controller can include a substantially planar substrate and a waveguide unit cell formed on the substantially planar substrate. The waveguide unit cell can include a first out-of-plane waveguide portion and a second out-of-plane waveguide portion coupled to the first out-of-plane waveguide portion. Each of the first and second out-of-plane waveguide portions can respectively include a core material layer arranged between a first optical cladding layer having a first stress-response property and a second optical cladding layer having a second stress-response property. The first and second stress-response properties can be different such that each of the first and second out-of-plane waveguide portions is deflected by a deflection angle.

A first resistor connected in parallel to a semiconductor optical modulator having first ends, the first resistor and first ends connected to a reference potential. A first end of a first transmission line is connected to second ends of the semiconductor optical modulator and the first resistor. A second transmission line is connected in series to the first transmission line and has an impedance lower than that of the first resistor. A first end of the second transmission line is connected to a second end of the first transmission line. A third transmission line is connected in series to the first and second transmission lines and has an end connected to a second end of the second transmission line, and has an impedance equal to that of the first transmission line. A second resistor and a capacitor are connected in series between the third transmission line and the reference potential.

The present invention provides a display device, which includes a color filter, a quantum dot (QD)-injected photonic crystal film, and a backlight module. The QD-injected photonic crystal film is formed by injecting QDs into a photonic crystal film. Due to the light guiding effect of the photonic crystal, the light emission efficiency of the QDs can be effectively improved. The photonic crystal film includes red, green, and blue light transmission zones. The QDs injected into red, green, and blue light transmission zones of the photonic crystal film are respectively red, green, and blue QDs, so that when white mixed light emitting from the backlight source reaches the QD-injected photonic crystal film, light transmission zones of the photonic crystal film allow only light of corresponding colors to pass such that the QDs contained therein emit light of corresponding colors. Further, these colors of light respectively transmit through the color filters of corresponding colors. Light of other colors is reflected back by the photonic crystal film to be subjected to scattering and re-reflection by the optical film for being subsequently allowed to transmit through the other two light transmission zones of photonic crystal film.
