Description

The present invention relates to a manufacturing method and a liquid crystal display device for displaying three-dimensional images or two-screen images, and particularly to a small-sized and easy-to-manufacture and economical liquid crystal display device for three-dimensional images or two-screen images. The present invention relates to a manufacturing method and a liquid crystal display device.

Conventionally, as a method of displaying a stereoscopic (3D) image without using special glasses, a lenticular method, a parallax barrier method, a method of slitting a light source, and the like have been proposed.
FIG. 4 is a schematic diagram showing the principle of stereoscopic video display by the parallax barrier method. The image observed by the observer is an image display device 5 comprising a liquid crystal display panel or a plasma display panel.
0 is formed. In order to enable stereoscopic viewing, the image display device 50 alternately includes left-eye pixels L on which left-eye images are displayed and right-eye pixels R on which right-eye images are displayed. Is formed. The positional relationship between the left eye pixel L and the right eye pixel R will be described later. The left-eye video and the right-eye video can be obtained by, for example, simultaneously shooting with two cameras for the left eye and the right eye, or are calculated from one image data by a logical operation. be able to. Both videos obtained in this way include parallax information necessary for humans to perform stereoscopic perception with binocular parallax.

In front of the image display device 50, a parallax barrier 51, which is a light shielding barrier, is disposed at a predetermined distance d from the image display device 50. In the parallax barrier 51, openings 51a are formed in a vertical stripe shape. The interval between the openings 51a and the interval d are set corresponding to the arrangement of the left-eye pixel L and the right-eye pixel R and the optimum observation position. The parallax barrier 51 separates the left-eye image and the right-eye image into left and right, and the separated images enter the observer's left eye 2L and right eye 2R, respectively. As a result, the observer can observe a stereoscopic image.

The above-described stereoscopic display device using the parallax barrier method is dedicated to three-dimensional display when the parallax barrier is fixed. Therefore, a parallax barrier provided on the front surface of the video display device is provided so that switching between two-dimensional (hereinafter referred to as “2D”) video display and three-dimensional (hereinafter referred to as “3D”) video display is possible. A 3D image display device has been developed that displays a 3D display by forming a black and white striped parallax barrier with this liquid crystal, and a 2D display by using a full transmission type. (See Patent Document 1 below).

A specific example of this conventional liquid crystal parallax barrier type stereoscopic image display apparatus will be described with reference to the drawings. FIG. 5 is a partially exploded cross-sectional view of a parallax barrier type stereoscopic image display device 60 having a liquid crystal parallax barrier disposed in front of a liquid crystal panel as an image display device. In FIG. 5, a transmissive liquid crystal display panel 63 in which display pixels are arranged via a first polarizing plate 62 is disposed on the surface of a backlight 61, and further a second polarizing plate 64 and a transparent plate 6.
A liquid crystal parallax barrier 67 is disposed via the fifth and third polarizing plates 66, and a fourth polarizing plate 68 is disposed on the surface of the liquid crystal parallax barrier 67.

The transmissive liquid crystal display panel 63 includes a rear glass substrate 69 located on the incident side of the backlight, a front glass substrate 70 located on the light emission side, a pixel electrode 71 formed on the inner surface of the rear glass substrate 69, and a front surface. It consists of a color filter 72 and a common electrode 73 formed on the inner surface of the glass substrate 70, and a liquid crystal 75 that is hermetically filled between the rear glass substrate 69 and the front glass substrate 70. The pixel electrode 71 is a right-eye pixel R so that a right-eye image and a left-eye image are formed.
The left-eye pixels L are alternately arranged, and the pixels are separated by vertical stripes (not shown).

Note that a transparent glass plate or an acrylic plate is used as the transparent plate 65. In order to set an optimum observation position at a predetermined distance from the stereoscopic image display device 60, the transmissive liquid crystal display panel 63 and the liquid crystal parallax are used. It is provided for maintaining a predetermined distance from the barrier 67.

The liquid crystal parallax barrier 67 is composed of two glass substrates each having an electrode 76 and a counter electrode 77 for forming a black and white stripe parallel to the stripes of the pixels L and R of the transmissive liquid crystal display panel 63. Liquid crystal 80 is filled in a sealed space sandwiched between 78 and 79, and is colorless and transparent when no voltage is applied to display a 2D image, and forms a black and white parallax barrier stripe when voltage is applied. Thus, 3D video display is performed. That is, the liquid crystal parallax barrier 67 is observed by designating its XY address by a control means such as a microcomputer and forming a barrier stripe of an arbitrary shape at an arbitrary position on the barrier surface in the case of 3D display. 3D images can be observed by a person.

Further, unlike the 3D video display device 60, a plurality of images are displayed in a superimposed manner on one screen, the first image is provided in the first observation area, and the second image is provided in the second observation area. Thus, a two-screen liquid crystal display device that can provide different images to a plurality of observers is also known. (See Patent Document 3 below).

Hereinafter, the conventional two-screen liquid crystal display device will be described with reference to the drawings. FIG. 6 is a cross-sectional view of a two-screen liquid crystal display device 90 according to a conventional example. As shown in FIG. 6, the two-screen liquid crystal display device 90 according to the conventional example has alternating first pixel columns 91a for displaying the first image and second pixel columns 91b for displaying the second image. A liquid crystal display panel 92 is provided. Here, the first and second pixel columns 91a and 91b are made up of pixels of a liquid crystal display device, for example. Further, a black matrix 93 is formed between the pixels of the first and second pixel columns 91a and 91b. A light shielding plate 94 made of metal or resin having a light shielding function is disposed above the liquid crystal display panel 92 via a transparent substrate such as a glass substrate having a thickness G (not shown). The light shielding plate 94 includes light shielding portions 95 and openings 96 that alternately extend in parallel to the first pixel row 91a and the second pixel row 91b.

Next, a mechanism for realizing two-screen display by the two-screen liquid crystal display device 90 configured as described above will be described. As shown in FIG. 6, an opening 96 of the light shielding plate 94 is passed through a first observation area A leftward from a position C directly in front of the liquid crystal display panel 92 that is separated from the surface of the light shielding plate 94 by a distance D. A first image is provided from the first pixel column 91a. At this time, since the second image of the second pixel row 91b is blocked by the light blocking portion 95 of the light blocking plate 94, the first observation area A
Not offered to.

On the other hand, a second image is provided from the second pixel row 91b through the opening 96 of the light shielding plate 94 to the second observation region B that is separated from the position C in front of the liquid crystal display panel 92 in the right direction. At this time, the first image of the first pixel row 91a is blocked by the light blocking portion 95 of the light blocking plate 94, and thus is not provided to the second observation region B. In this way, a two-screen display is performed in which the first image is provided in the first observation area A and the second image is provided in the second observation area B.

Also in such a two-screen liquid crystal display device 90, the same as the liquid crystal parallax barrier 67 used in the 3D video display device 60 described above as the light shielding plate 94 in order to switch between the normal one-screen display and the two-screen display. A configuration can be used. As the liquid crystal panel used as the liquid crystal parallax barrier 67 or the light shielding plate 94, a normal liquid crystal display panel can be used as it is.

In the liquid crystal display device 10, the distance L between the liquid crystal 14 of the liquid crystal display panel 15 and the liquid crystal 18 of the liquid crystal shutter or liquid crystal barrier 19 is large because the observation position is away from the display surface in the case of the medium size / large size. Normally, a transparent plate as indicated by reference numeral 65 in FIG. 5 is arranged so that L is constant. However, in the case of a small liquid crystal display device for a cellular phone in recent years, since the observation position is very close to the display surface, the value of L is also 10

Since the thickness of 17 is large and the difference in thickness between the two substrates is large, it is very difficult to perform the dividing process together.

The present invention has been made to solve such problems of the prior art.
