  • Patent number: 12019334
    Abstract: A liquid crystal display device prevents light leakage in a black display of a projected image when a light source reaches a higher temperature, and displays a high-quality image without any lost sense of reality. The device includes a light-transmissive liquid crystal display element including two glass substrates and a liquid crystal layer sealed between the glass substrates, a backlight device that emits light toward one glass substrate in the liquid crystal display element, an emission-light polarizing plate on the other glass substrate, an incident-light polarizing plate on the one glass substrate, and a polarizer being a plate and including a base layer including a glass substrate and a metal layer stacked on the base layer and having a polarization function. The polarizer is located with the base layer facing the incident-light polarizing plate. The base layer is thicker than each of the glass substrates.

  • Patent number: 11961429
    Abstract: A head-up display includes a display panel, a reflective optical element, a controller, and an obtainer. The display panel displays a first image. The reflective optical element reflects image light from the first image displayed by the display panel. The controller controls a position at which the first image is displayed on the display panel. The obtainer obtains, as positional information, a position of an eye of a user. The controller changes the position at which the first image is displayed on the display panel in accordance with the positional information.

  • Publication number: 20240121374
    Abstract: A three-dimensional display device includes a display, a barrier, and a controller. The display displays a parallax image including a right-eye viewing image and a left-eye viewing image. The barrier defines a traveling direction of image light of the parallax image. The controller causes a black image to appear between the right-eye viewing image and the left-eye viewing image based on a parallax value of the parallax image.
