Claims (3)

A plurality of pixels for controlling light transmission are arranged in a plurality of rows and columns, and the operation voltage of each pixel corresponding to image data is sequentially applied to each of a plurality of pixel rows composed of a plurality of pixels arranged in the row direction. A liquid crystal display element for applying and displaying an image;
The liquid crystal display element is disposed on the side opposite to the observation side, and light is incident on one side opposite to the liquid crystal display element from one end side in a direction parallel to the pixel row, and the light passes in the other end direction. A backlight that forms a light guide space ;
With
The backlight is
A plurality of light emitting elements that are arranged to face one end of the light guide space and emit light toward the light guide space;
A micromirror array panel provided on a surface facing the liquid crystal display element;
Consists of
The micromirror array panel is:
A state of lying on the surface;
A state in which the light rises obliquely toward the other end direction of the light guide space with respect to the surface and reflects light incident on the light guide space from the one end side toward the liquid crystal display element;
A plurality of micromirrors controlled by the above are arranged in a plurality of rows,
Respectively for each corresponding plurality of micro-mirrors in a plurality of pixel rows before Symbol liquid crystal display element is controlled to turn the rising state sequentially in synchronization with the application of the operating voltage to the plurality of pixel rows of the liquid crystal display device A liquid crystal display device. The backlight on the side facing the liquid crystal display device of the micromirror array panel, the further includes a transparent plate which is disposed with a gap between the micro-mirror array panel, the light guide space the liquid crystal display device according to claim 1, characterized in that it is formed by a gap between the transparent plate and before Symbol micromirror array panel.   Between the backlight and the liquid crystal display element, there is provided a diffusion layer for diffusing the light reflected toward the liquid crystal display element by the micromirror controlled to the rising state of the micromirror array panel. The liquid crystal display device according to claim 1 or 2.
