摘要： A liquid crystal display device includes, in sequence, a backlight, a first substrate including a color filter layer, a liquid crystal layer containing a liquid crystal composition, and a second substrate. The liquid crystal composition contains a liquid crystal compound having a phenyl group and a conjugated bond group. The phenyl group has a halogen atom substituted for at least one hydrogen atom. The conjugated bond group is conjugated with the phenyl group to form a continuous conjugated system.

摘要： An X-ray image capturing apparatus includes a photoelectric conversion element, a TFT, a gate drive circuit, a control circuit, and a filter section. The TFT is connected to the photoelectric conversion element. The gate drive circuit supplies a gate signal to a gate electrode of the TFT. The control circuit supplies a control signal to the gate drive circuit. The filter section attenuates a component of the gate signal or the control signal that has a frequency lower than a prescribed frequency.

摘要： Provided is an optical element including: a first liquid crystal cell including first liquid crystal molecules and a first electrode; and a second liquid crystal cell including second liquid crystal molecules and a second electrode, the first and second electrodes disposed to enable switching between a first state twist-aligning the second liquid crystal molecules and vertically aligning the first liquid crystal molecules and a second state twist-aligning the first liquid crystal molecules and vertically aligning the second liquid crystal molecules. Alignment directions of the second liquid crystal molecules near a third substrate and the second liquid crystal molecules near a fourth substrate in the first state are respectively at azimuthal angles resulting from a ¼ turn in the same direction of azimuthal angles of alignment directions of the first liquid crystal molecules near the first substrate and the first liquid crystal molecules near the second substrate in the second state.

摘要： In an image processing device, for each of one or two or more picture elements among a plurality of picture elements, the one or two or more picture elements having an input grayscale value included in the input image data being equal to or less than a first predetermined value, the second panel data correction unit corrects the second aperture ratio of each of at least one pixel among the plurality of pixels, the at least one pixel facing the one or two or more picture elements, so that an actual transmittance gets closer to a theoretical transmittance, and the first panel data generation unit generates the first aperture ratio for each of the plurality of picture elements by dividing a normalized input grayscale value included in the input image data by a normalized luminance included in the panel luminance distribution data.
