The invention discloses a display device and a vehicle, and belongs to the technical field of display. The display device includes an image generation unit, an imaging unit, and a polarization transmission unit. The image generation unit is used for providing a light beam, and the light beam carries image information and is linearly polarized light with a first polarization direction. The imaging unit is used for converting at least part of the light beam into linearly polarized light in a second polarization direction and forming a virtual image based on the linearly polarized light in the second polarization direction, and the second polarization direction intersects with the first polarization direction. The polarization transmission unit is located on a viewing path of the virtual image. The polarization transmission unit is configured to transmit at least part of the linearly polarized light in the second polarization direction and block the linearly polarized light in the first polarization direction. A user can be prevented from seeing two display pictures at the same time, and the display effect is improved.

    本申请公开了一种显示装置和交通工具,属于显示技术领域。该显示装置包括图像生成单元、成像单元和偏振透射单元。图像生成单元用于提供一光束,光束携带图像信息且光束为具有第一偏振方向的线偏振光。成像单元用于将光束的至少部分转换为具有第二偏振方向的线偏振光,以及基于第二偏振方向的线偏振光形成虚像,第二偏振方向与第一偏振方向相交。偏振透射单元位于虚像的观看路径上。偏振透射单元被配置为透射第二偏振方向的线偏振光的至少部分以及阻挡第一偏振方向的线偏振光。本申请可以避免用户同时看到两个显示画面,提高显示效果。
