| 摘要 |
This liquid-crystal display device is provided with a first electrode, a second electrode, a liquid-crystal layer, and a light-guide plate. The second electrode is opposite the first electrode. The liquid-crystal layer is disposed between the first and second electrodes. In a no-voltage state wherein a voltage is not applied between the first and second electrodes, the liquid-crystal layer is optically isotropic, and in a voltage-applied state wherein a voltage is applied between the first and second electrodes, the liquid-crystal layer becomes optically anisotropic. The light-guide plate is disposed opposite the liquid-crystal layer and has a first end surface and a first principal surface. Light that enters the light-guide plate from the first end surface is propagated in a first direction and outputted diagonally towards the liquid-crystal layer from the first principal surface, which faces the liquid-crystal layer. |
