A display apparatus and a liquid crystal display device are provided. The display apparatus comprises a display device for displaying an image and a diffractive optical element. The diffractive optical element comprises pixel unit regions. Each of the pixel unit regions has a long pixel side and a short pixel side adjacent to each other. The diffractive optical element is disposed on a light emitting side of the display device and comprises first grating regions and second grating regions. The first grating regions have a first diffraction grating. The second grating regions have a second diffraction grating. An azimuth angle of the first diffraction grating is different from an azimuth angle of the second diffraction grating.

Display apparatus and liquid crystal display device

A display device is disclosed. The display device includes a display and a diffractive optical element (DOE). The display is used to show an image. When a user looks at the image within a first viewing angle range, he can see a first observed image, and when he looks at the image within a second viewing angle range, he can see a second observed image. The diffractive optical element is disposed in the lighting direction of the display to diffract the light constructing the first observed image to the second viewing angle range, thereby converting the first observed image into a third observed image and converting the second observed image into a fourth observed image at the same time.

Display Device

A liquid crystal display (LCD) is provided and includes an liquid crystal panel, a diffraction plate, a first polarizer, a second polarizer, a first brightness enhancement film (BEF), and a second BEF. The diffraction plate is disposed on a first surface of the liquid crystal panel and has a diffractive direction. The first polarizer is disposed between the diffraction plate and the liquid crystal panel and has a first absorption axis. The second polarizer is disposed on a second surface of the liquid crystal panel opposite to the first surface and has a second absorption axis perpendicular to the first absorption axis. The first BEF has a first light-collecting direction. The second BEF has a second light-collecting direction perpendicular to the first light-collecting direction. The first light-collecting direction is parallel or perpendicular to the diffractive direction or the first absorption axis.

Liquid crystal display

A display apparatus is provided. The display apparatus comprises a display device for displaying an image and a diffractive optical element. The diffractive optical element is disposed on a light emitting side of the display device. The diffractive optical element comprises first grating regions. Each of the first grating regions has first diffraction gratings having a constant cycle space and the same azimuth angle. An area of the first grating regions occupies 17.5%&#x2dc;94% of an area of the diffractive optical element.
