In a display device for projecting an image on a screen by a projection lens, the reflected light obtained by optically modulating an image adjusted to each color by the DMD, the rotating color filters are arranged in even-numbered pairs with one pair of three primary color filters. And
The three-dimensional image display device is configured by changing the polarization direction of light for each pair according to the images for the right eye and the left eye. With this configuration, it is possible to change the deflection angle of each projected image of the image for the right eye and the image for the left eye, alternately switch the images at a speed at which the afterimage phenomenon works, and change the polarization direction of the left eye and the right eye. A stereoscopic image can be recognized by looking at the images projected by the polarized glasses that have been combined. With the above structure, a stereoscopic display device can be provided without largely changing the basic structure of a display device using a DMD. The invention according to claim 2 of the present invention is provided with a polarizing filter rotatably held in an optical path of the image display device, and sets the polarizing filter at a predetermined angle at a timing of switching between images for the left eye and the right eye. This is a three-dimensional image display device to be rotated. With this configuration, images for the left eye and the right eye, each having a different deflection angle, can be projected on the screen, and by viewing the projected images with polarizing glasses that match the polarization directions of the left and right eyes respectively. 3D images can be recognized. According to the invention of claim 3 of the present invention, an image for the right eye is formed by the first DMD, and an image polarized through the first polarizing plate and an image for the right eye by the second DMD are formed. It is configured to form and project an image polarized through a second polarizing plate having a polarization angle different from that of the first polarizing plate. With this configuration, the polarization angles of the respective projected images of the right-eye image and the left-eye image can be changed. Therefore, the projected composite image is polarized by matching the polarization directions of the left-eye image and the right-eye image. There is an effect that a stereoscopic image can be recognized by looking through the glasses.

FIG. 3 shows a configuration diagram of a stereoscopic image display device using a rotating polarizing plate. The light from the white light source 11 is condensed by the condensing lens 12 on the rotating color filter 21 having no polarization function, and the light that has been serially color-modulated in the order of red, green, and blue through the condenser lens 1 is passed therethrough.
4 to the DMD 15, and the reflected light, which is light-modulated by the DMD into an image corresponding to each color, is transmitted to the motor 22 and the belt 2.
3, an image is projected on a screen by the projection lens 16 via a rotating polarizing filter 24 which holds the polarizing filter rotatably. In the above-described configuration, the light color-modulated in the order of red, green, and blue by the rotating color filter 21 is defined as one cycle, and the rotating polarization filter is switched as shown in FIG. By rotating 24 by 90 degrees, images for the left eye and the right eye, each having a different polarization angle, can be projected on the screen, and the images are projected by polarizing glasses in which the polarization directions of the left and right eyes are respectively adjusted. A stereoscopic image can be recognized by viewing the image. As shown in FIG. 5, the rotation axis 26 and the polarization direction 27 of the polarization filter 25 are set to 45.
Alternatively, the polarization direction may be shifted by 90 degrees by inverting the polarization filter along the rotation axis. Also,
After image processing the red, blue, and green light separated by the three DMDs, an image display device of a type that synthesizes colors is equipped with a rotating polarization filter, and switches between images for the left and right eyes. A three-dimensional image display device can also be configured by rotating the rotating polarization filter 24 by 90 degrees as shown in FIG. Further, the same effect can be obtained even if a rotating polarization filter is attached to the optical path of the CRT type image display device (to cover the display surface of the CRT in the case of a direct view type). The rotary polarizing filter 24, the motor 22, and the timing control circuit 28 (timing can be obtained from an image signal) according to the present invention can be externally attached to a lens unit such as a projection device in the form of a lens cap, or a screen cover of an image display device. It may be added later. In the above embodiment, the polarization angles of the left and right images are set to 90 degrees, but there is no restriction on the polarization angle as long as the left and right images can be separated.

D (Digital Micromirror Display), a display device that projects an image on a screen by using a projection lens, and reflects the reflected light obtained by optically modulating the image adjusted to each color by the DMD. A three-dimensional image display device characterized in that the three filters are arranged in even pairs as one pair, and the polarization direction is changed for each pair.
た偏光フィルタを装備し、左眼用と右眼用の画像を切り
替えるタイミングで、偏光フィルタを規定の角度回転さ
せることを特徴とする立体画像表示装置。2. An image display device comprising a polarizing filter rotatably held in an optical path, wherein the polarizing filter is rotated by a predetermined angle at a timing of switching between an image for the left eye and an image for the right eye. Stereoscopic image display device.
し、第１の偏光板を介して偏光した画像と、第２のＤＭ
Ｄにより右眼用の画像を形成し、第１の偏光板と偏光角
度の異なる第２の偏光板を介して偏光した画像を合成し
て投影することを特徴とする立体画像表示装置。3. An image for the right eye is formed by a first DMD, and an image polarized through a first polarizing plate and a second DMD.
A three-dimensional image display device, wherein an image for the right eye is formed by D, and an image polarized by way of a first polarizing plate and a second polarizing plate having a different polarization angle is synthesized and projected.
