Devices including nematic liquid crystal-forming molecules are disclosed. The molecules include one or more dipoles and exist in a ferroelectric nematic state. Exemplary devices can further include an electrode for applying an electric field in, for example, and in-plane direction.

A display may include illumination optics, a ferroelectric liquid crystal on silicon (fLCOS) panel, and a waveguide. The display may include a temperature sensor that gathers temperature sensor data. Control circuitry may select a non-square wave drive voltage waveform based on the gathered temperature sensor data and/or based on frame history information for the fLCOS display panel. The control circuitry may control the fLCOS panel to produce image light by driving the fLCOS panel using the selected non-square wave drive voltage waveform. The non-square wave drive voltage waveform may be an overdrive waveform or an underdrive waveform. This may serve to optimize the reflectance of the fLCOS display panel and thus the optical performance of the display module regardless of operating temperature and frame history.

Provided is a display panel, which includes a first LCD panel and a second LCD panel. The first LCD panel is disposed in opposite to and atop the second LCD panel. Each sub-pixel of the first LCD panel is correspondingly aligned with each sub-pixel of the second LCD panel. The second LCD panel includes ferroelectric liquid crystals. Also provided is a display device having such display panel. The invention can effectively enhance the transmittance of the backlight and elevate the luminance, thereby reducing power consumption and saving cost.

A virtual image display device or an optical unit includes a display configured to emit video light, and a polarization-selective lens that is disposed facing the display and that has a refractive power that selectively acts on polarized light of the video light. The polarization-selective lens includes, in order from a display side, a polarizing diffractive lens having a positive refractive power with respect to the video light that is circularly polarized light and having a negative refractive power with respect to external light that is circularly polarized light, and an auxiliary lens having a positive refractive power equivalent to a refractive power of the polarizing diffractive lens.
