    摘要： 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.

    摘要： A display device includes: a first panel including a first image-forming surface for forming a first image visually recognized by a user and a plurality of first pixels; a second panel including a second image-forming surface for forming a second image visually recognized by the user and a plurality of second pixels; and a half-wavelength plate located between the first image-forming surface and the second image-forming surface. The half-wavelength plate includes an optical axis, is configured to be capable of transmitting incident light from either one panel of the first panel and the second panel, and of emitting light as emission light to the other panel. A polarization direction of the emission light from the half-wavelength plate is determined based on a polarization direction of the incident light on the half-wavelength plate and a direction of the optical axis.

    摘要： A display device is switchable between 3D image display and 2D image display. The display device includes a first display panel, a second display panel, a controller, and an optical system. The first and second display panels each include subpixels arranged in a grid. The controller performs switching and/or is configured to perform switching between multiple display modes including a first display mode for displaying a 2D image and a second display mode for displaying a parallax image on the first display panel, and switches and/or is configured to switch a drive mode of the second display panel between multiple drive modes including a first drive mode corresponding to the first display mode and a second drive mode corresponding to the second display mode.

    摘要： A display device includes a first display panel, a second display panel, and a controller. The first display panel includes a plurality of first subpixels which are aligned in a grid-like layout in an x-direction and a y-direction. The second display panel includes a plurality of second subpixels which are aligned in a grid-like layout along the x-direction and the y-direction at a same pitch as that of the plurality of first sub pixels. The controller controls the plurality of first subpixels and the plurality of second subpixels based on image data. At least one of the first display panel and the second display panel that is arranged on a user side is a transmissive display panel. Each of the plurality of first subpixels is superimposed on any of the plurality of second subpixels in a normal direction of the first display panel.
