This document discloses a stereoscopic image display device. In the image display device, a display device displays a first image data and a second image data in a time-dividing manner. A switchable retarder panel is configured to control light emitted from the display device and is made of electrically controlled birefringence (ECB) liquid crystals. Polarization glasses polarize the light emitted from the switchable retarder panel. The polarization glasses comprise a left eyeglass comprising a polarizer having a tilt of 45&#xb0; about a light absorbing axis, and a right eyeglass comprising a polarizer having a tilt of 135&#xb0; about the light absorbing axis.

A display device and a method of manufacturing the same are disclosed. The display device includes a first panel, a panel supporter including a bottom part in which the first panel is received, a first pad that is positioned on the bottom part of the panel supporter and attaches the first panel to the panel supporter, a second panel positioned on the first panel, a cover including a surface part covering a partial outer wall of the second panel, and a second pad that is positioned under the surface part of the cover and attaches the second panel to the cover.

Display device and method of manufacturing the same

This document discusses a stereoscopic image display device. In the stereoscopic image display device, a display device displays first image data during an N(where N is a positive integer) frame period and displays second image data during an (N+1)frame period. A polarization conversion device converts light which is output from the display device into first polarized light in response to a first driving voltage during the Nframe period and converts light which is output from the display device into a second polarized light in response to a second driving voltage during the (N+1)frame period. The phase of a point of time at which scanning of at least one of the first and second image data starts is differently synchronized with the phase of a point of time at which scanning of at least one of the first and second driving voltage starts.

A stereoscopic image display device comprises a liquid crystal panel alternately displaying a first image and a second image, the first and second images being changed at first transition durations every frame, a polarization control panel disposed on the liquid crystal panel and changing polarization states at second transition durations, polarization glasses enabling the displayed first and second images to be viewed via the polarization control panel, and a backlight unit providing light to the liquid crystal panel and having black durations where the light is not provided to the liquid crystal panel.

A stereoscopic image display device comprises a display panel which is controlled so that image frame data are stored for frame intervals and are displayed for blank intervals, each of the blank interval being between the frame intervals; a polarization control panel which positioned on the display panel and converts a polarization state of light passing through the display panel; and polarization glasses which creates stereoscopic images by restricting the light converted by the polarization control panel and reaching each eye.

Three-dimensional image display device

An embodiment of the present invention provides a stereoscopic image displaying apparatus comprising a displaying panel that receives image data displaying an image and black data displaying no image for each frame section, and a polarization control panel that is located over the displaying panel and changes a polarization state.
