DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stereoscopic image display device capable of observing a color stereoscopic image without using special glasses.

[0002]

2. Description of the Related Art Conventionally, a parallax barrier method as shown in FIG. 6 has been proposed as a method for displaying a stereoscopic image without using glasses.

In FIG. 6, reference numeral 1 denotes a display panel such as a liquid crystal panel for displaying a color image, and reference numeral 2 denotes a barrier substrate which allows a part of light from each picture element of the display panel 1 to pass. The arrangement pattern of the picture elements of the display panel 1 is such that a red picture element R1 for the left eye and a green picture element G for the right eye are sequentially arranged in the horizontal direction.
2. Blue picture elements B1 for the left eye, red picture elements R2 for the right eye, green picture elements G1 for the left eye, and blue picture elements B2 for the right eye are repeatedly arranged in this order.

The barrier substrate 2 is a slit-shaped substrate in which a number of vertically long openings 2a for transmitting light from the respective picture elements of the display panel 1 are formed via barrier portions 2b for shielding light.

[0005] In the stereoscopic image display device having such a configuration,
In front of the display surface, only light emitted from picture elements R1, G1, B1 for the left eye enters through the opening 2a of the barrier substrate 2, and picture elements R2, G2, The light emitted from B2 is blocked by the barrier portion 2b and does not enter, and conversely, only the light emitted from the right-eye picture elements R2, G2, and B2 passes through the opening 2a of the barrier substrate 2. The light 3 which enters through the light source and is emitted from the picture elements R1, G1, and B1 for the left eye is shielded by the barrier portion 2b and does not enter.
2 are formed.

The distance between the region 31 and the region 32 is set to be the distance between human eyes (eg, 65 mm), the left eye of the observer is positioned in the region 31, and the right eye is positioned in the region 31. By positioning at 32, the observer can recognize only the picture elements R1, G1, and B1 for the left eye with the left eye, and can recognize only the picture elements R2, G2, and B2 for the right eye with the right eye. , You can watch 3D images.

In the above-described stereoscopic video display device, the pitch between the left-eye picture element and the right-eye picture element of the display panel is P.
(Equal to the pixel pitch P), the distance between human eyes is E, the distance from the display surface of the display panel 1 to the barrier substrate 2 is t1,
Assuming that the appropriate viewing distance from the barrier substrate 2 to the regions 31 and 32 is L1, P: t1 = E: L1, and the following equation 1 holds.

[0008]

(Equation 1)

That is, the suitable viewing distance L1 from the barrier substrate 2 to the regions 31 and 32 is inversely proportional to the pitch P between the left-eye picture element and the right-eye picture element. However, for example, the pixel pitch is 0.0175 mm, and the thickness of the glass substrate is 0.85 mm.
When a liquid crystal panel of mm (this value is an air-equivalent distance in consideration of the refractive index of the glass substrate) is used, and a barrier substrate is bonded to the glass substrate of the liquid crystal panel to form the above-described stereoscopic image display device. , P = 0.0175 mm, t1 =
0.85 mm, and the suitable viewing distance L1 is as large as 3 m or more. For this reason, there is a problem that the observer cannot observe the stereoscopic video unless the viewer is far away from the display screen, and cannot observe the stereoscopic video with a sense of reality.

FIG. 7 shows a conventional stereoscopic image display device in which a barrier substrate 4 is arranged on the light incident side of the display panel 1. The barrier substrate 4 is a slit-shaped substrate in which a number of vertically long openings 4a for transmitting light from the flat light source 5 are formed via barrier portions 4b for shielding light.

In the stereoscopic image display device having such a configuration,
The light emitted from the flat light source 5 becomes slit-like light passing through the opening 4a of the barrier substrate 4. This allows
In front of the display panel 1, only light that passes through the left-eye picture elements R1, G1, and B1 of the slit-shaped light enters, and passes through the right-eye picture elements R2, G2, and B2. A region 61 in which light does not enter, and vice versa, picture elements R2, G2,
Only light that has passed through B2 enters, and picture elements R1, G for the left eye
1, a region 62 where light passing through B1 does not enter is formed.

The distance between the region 61 and the region 62 is set to be the distance between human eyes (for example, 65 mm), the left eye of the observer is positioned in the region 61, and the right eye is positioned in the region 61. By locating at 62, the observer can recognize only the picture elements R1, G1, and B1 for the left eye with the left eye, and can recognize only the picture elements R2, G2, and B2 for the right eye with the right eye. , You can watch 3D images.

In the three-dimensional image display device as described above, the pitch between the picture element for the left eye and the picture element for the right eye is P (picture element pitch P
E), the distance between the human eyes is E, the distance from the barrier substrate 4 to the display panel 1 is t2, and the appropriate viewing distance from the display panel 1 to the regions 61 and 62 is L2.
t2 = E: L2 + t2, and the following equation 2 holds.

[0014]

(Equation 2)

That is, the suitable viewing distance L from the display panel 1 to the regions 61 and 62 is inversely proportional to the pitch P between the left-eye picture element and the right-eye picture element. However, for example, similarly to the stereoscopic image display device of FIG.
A liquid crystal panel having a thickness of 75 mm and a glass substrate thickness of 0.85 mm (this value is an air-equivalent distance in consideration of the refractive index of the glass substrate) is used, and a barrier substrate is adhered to the glass substrate of the liquid crystal panel. When configuring a video display device,
P = 0.0175 mm, t1 = 0.85 mm, and the suitable viewing distance L2 is 3 m or more. For this reason, there is a problem that the observer cannot observe the stereoscopic video unless the viewer is far away from the display screen, and cannot observe the stereoscopic video with a sense of reality.

[0016]

And a right-eye picture element area are alternately formed in the left-right direction, and a light-transmitting portion that transmits light from a light source to the barrier substrate and a light-shielding portion that shields light of an image from the display panel are formed on the barrier substrate. Color filters having substantially the same color as the colors of the picture elements of the display panel are provided in the translucent portion so as to have the same arrangement as the colors of the picture elements. Light that has passed through a color filter of substantially the same color among the color filters provided in the light-transmitting portion of the barrier substrate. Only stereoscopic image display apparatus characterized by separating into a light from pixel regions for light and the right eye from the pixel area for the left eye by forming a. 3. The display panel according to claim 1, wherein the picture elements of different colors for the left eye and the right eye are a red picture element, a green picture element, and a blue picture element. 3. The three-dimensional image display device according to claim 1, comprising a red filter, a green filter, and a blue filter.
