- the three-dimensional image display device 30 has a frame 28 for shielding light from the surroundings. Due to the presence of incident light from the surface of the image display device 30, stray light exists inside the three-dimensional image display device 30, and this stray light enters the side force of the transparent plate 20 and is By emitting light from the vicinity of the boundary of the effective display area of Lux Noria 24, blurring or black display as described above may not be complete black display, leading to deterioration of display quality such as I learned that.

- the total reflected light ⁇ does not affect the display quality of the three-dimensional image display device 30, but the emitted light ⁇ comes out to the observer side via the parax noria 24, so that the three-dimensional image display device 30 is effective.
- the blurring near the boundary of the display area or the complete black display does not occur, which causes a bad influence on the display quality.
- the thickness of the transparent plate 20 is thin, and the outgoing light ⁇ exists only near the end of the transparent plate 20, the boundary of the effective display area of the three-dimensional image display device 30 is obtained. It does not adversely affect the display quality near the part.

- the conventional apparatus for manufacturing an image display device such as a liquid crystal display panel is suitable for performing various kinds of processing on a flat surface such as a glass substrate or an acrylic substrate! Since it is not suitable for processing the side surface of the transparent plate 20, it cannot be converted as it is because the light shielding member is provided on the side surface of the transparent plate 20. There is a problem that a space for installing the dedicated device is required.
- the present inventors have developed a configuration that can prevent deterioration of display quality with respect to an end surface of an effective area of a three-dimensional image display device even when using a conventional apparatus for manufacturing an image display device such as a liquid crystal display panel.

- the light shielding member is provided on the surface of the glass substrate on the side of the liquid crystal parallax barrier facing the transparent plate.
- the invention according to claim 9 of the present application is characterized in that, in the stereoscopic image display device according to any one of claims 5 to 8, the light shielding member also has a black mask force.
- the invention of the stereoscopic video display device of the present application has excellent effects as described below. That is, according to the three-dimensional image display device according to claim 1 of the present application, a light-shielding member is provided in the vicinity of the boundary of the effective display area of the parallax barrier to shield light that has also entered the lateral force of the transparent plate. Therefore, even if the thickness of the transparent plate becomes thicker and the side force of the transparent plate causes the incident stray light to normally exit the parallax barrier force, this light is blocked by the light shielding member. Since it does not come out of parallax noria, the display quality is such that the image is blurred near the boundary of the effective display area of the stereoscopic image display device and the black display part is not completely black display Deterioration does not occur.

If the present invention is applied to the case where the distance is 5 cm or more, the effect is remarkably exhibited.
- the upper limit of the thickness of the transparent plate is not critical because it is determined by the distance between the observer and the stereoscopic image display device. As the distance increases, the thickness of the transparent plate must be increased, and even if the thickness of the transparent plate is too large, the weight increases and it becomes impractical, so the upper limit is 10 cm. It is preferable to set the degree.
