Abstract
The present invention may provide a stereoscopic image display device capable of preventing crosstalk or reduction of viewing angles upon displaying stereoscopic images, and improving image quality such as contrast ratio; an optical filter for the stereoscopic image display device; polarizing glasses for observing stereoscopic images; or a method of improving stereoscopic image quality.
Claims23
A stereoscopic image display device, comprising:
- an image display part which is capable of generating image signals comprising image light for the right eye and image light for the left eye, and is also capable of transferring them to the observer side;
- and
- a retardation film that has phase difference in the thickness direction and is arranged such that the image signals transferred from the image display part may pass through the retardation film according to the thickness direction and then be transferred to the observer's side.
An optical filter for a stereoscopic image display device comprising:
- a polarization control layer which is capable of controlling image signals, comprising image light for the right eye and image light for the left eye, such that the image light for the right eye and image light for the left eye have polarization states different from each other when the image signals enter, and is also capable of emitting them;
- and
- a retardation film which is attached to the side of the polarization control layer, from which the image signals are emitted, and which has a phase difference in the thickness direction.
Polarizing glasses that are used for observing a stereoscopic image comprising a lens for the right eye and a lens for the left eye, wherein the lenses for the right eye and the left eye each comprise a retardation film having a phase difference in the thickness direction and a polarizing plate.
A method for improving the quality of stereoscopic images displayed from an image display part, which is capable of generating image signals, comprising image light for the right eye and the left eye, to be viewed by the right eye and the left eye of an observer respectively, and is also capable of then transferring them to the observer's side, comprising a step of disposing a retardation film having a phase difference in the thickness direction such that the image signals emitted from the image display part may pass through the retardation film in the thickness direction and then be transferred to the observer's side.
