In addition,
In the present embodiment, the light guide plate fixing frame 56 and the reflector 66 are integrally formed with one side common.

The liquid crystal panel 14 is disposed between the panel fixing frame 12 and the spacer 30 as shown in FIG. In the liquid crystal panel 14, liquid crystal is sealed between the active matrix substrate 15 and the opposing substrate 24, and a polarizing plate 85 is provided on the outer surface of the active matrix substrate 15 and the opposing substrate 24.
(The polarizing plate 84 on the rear side is not shown in FIG. 1) and is formed by being attached thereto. The active matrix substrate 15 as a first substrate includes a facing region facing the facing substrate 24 and an overhang region 140 not facing the facing substrate 24. The overhang region 140 is formed to extend from the facing region, and includes a terminal portion 81 as shown in FIG. 2 which is a schematic plan view of the liquid crystal panel 14.
The terminal portion 81 has a wiring board 82 such as an FPC.
(Flexible wiring board) is connected.

The liquid crystal panel 14 has the overhang area 1
The active matrix substrate 15 also has a non-facing region 144 where the active matrix substrate 15 does not face the

2 is to increase the contact area between the active matrix substrate 15 and the opposing substrate 24 in order to prevent the intrusion of air or the like from outside in order to realize highly reliable sealing. It is formed as a protruding portion having a shape rising from the end face.

As described above, the sealing portion 22 of the liquid crystal panel 14
Does not protrude from the end face 23 of the active matrix substrate 15. Therefore, the size of the liquid crystal display device 10 including the liquid crystal panel 14 can be reduced, and the frame member for holding and protecting the liquid crystal panel 14 does not need to be processed to avoid the sealing portion 22, thereby facilitating the manufacture.

Further, there is a low possibility that the reliability of the liquid crystal display device 10 is reduced due to the sealing portion 22 being damaged by interference with other members.

Further, the terminal portion 81 is connected to the first liquid crystal panel 14.
Since the sealing portion 22 formed in the overhanging region 140 and closing the liquid crystal injection opening is formed on one side other than the side corresponding to the overhanging region 140, the liquid crystal injection opening is on a different side from the terminal portion 81. It will be provided in. Therefore, no swelling due to the sealing portion occurs in the overhanging region 140, and when the flexible wiring board 82 or the like is crimped to the terminal portion 81, uniform squeeze is prevented by such swelling. Therefore, the wiring board 82 can be securely connected to the terminal portion 81 by crimping.

Further, when the liquid crystal is filled from the liquid crystal injection port, the contamination of the terminal portion 81 can be easily avoided, and the electric resistance in the electrical connection of the terminal portion 81 due to the contamination of the terminal portion 81 by the liquid crystal can be easily reduced.

Either is formed. The liquid crystal panel 14 will be described in further detail later.

The backlight unit 40 as a surface light source unit is disposed between the spacer 30 and the shield case 72 as shown in FIG. The backlight unit 40 includes a fluorescent tube 50 as a light source unit, a light guide plate 44, and a lens sheet 42. The output of an inverter (not shown) is connected to the fluorescent tube 50 via a connection section 51 for connecting a power supply of a predetermined voltage. The light guide plate 44 has a fluorescent tube 50 disposed along one end surface 45 thereof, and guides light from the fluorescent tube 50 toward the entire display area of the liquid crystal panel 14. The light guide plate 44 has a thicker wedge-shaped cross-sectional shape on the fluorescent tube 50 side.
By providing the light guide plate 44 with such a shape, the amount of light emitted from the light guide plate 44 toward the liquid crystal panel 14 is made uniform near the fluorescent tube 50 and at a position away from the fluorescent tube 50. The lens sheet 42 is disposed on the front side of the light guide plate 44 to improve light use efficiency.

The inverter (not shown) is disposed on the back side of the light guide plate fixing frame 56 and supplies power to the fluorescent tubes 50 of the backlight unit 40. The inverter outputs, for example, an input 5 V DC voltage as a 250 V, 100 kHz AC voltage, and supplies the AC voltage to the fluorescent tube 50. Since the inverter is disposed immediately behind the backlight unit 40 across the light guide plate fixing frame 56 and near the position where the fluorescent tube 50 is disposed, the wiring to the connection portion 51 of the fluorescent tube 50 can be shortened. Can be. Thereby, the leakage current from the wiring between the inverter and the fluorescent tube 50 is reduced, and the fluorescent tube 50 can emit light with high energy efficiency.

As shown in FIG. 1, the panel fixing frame 12 has a frame portion 12a and a display window 13 having a size corresponding to the display area of the liquid crystal panel 14, and fixes the liquid crystal panel 14 from the front side. Physically protected.

I have. As described above, by disposing the spacer 30 between the liquid crystal panel 14 and the backlight unit 40, a predetermined gap is formed between the liquid crystal panel 14 and the backlight unit 40. Occurs, and
Moiré caused by optical interference between pixels of the liquid crystal panel 14 and stripes of the lens sheet 42 of the backlight unit 40 is prevented. Further, by disposing the spacer 30 between the liquid crystal panel 14 and the backlight unit 40, a gap is formed between the liquid crystal panel 14 and the backlight unit 40, and the liquid crystal panel 14 and the lens sheet 42 are in contact with each other. Without doing so, it is possible to prevent the lens sheet 42 from being damaged or damaged.

Further, the above-mentioned frame portion 30 of the spacer 30
FIG. 3A is a cross-sectional view schematically showing the liquid crystal panel 14, the spacer 30, and the backlight unit 40, as shown in FIG.
A frame portion 30a is formed at a position corresponding to 0. As described above, since the frame portion 30 a of the spacer 30 located between the liquid crystal panel 14 and the backlight unit 40 is formed at a position corresponding to the peripheral circuit region 170 located around the display region 130, Light unit 40
Light and heat that reach the peripheral circuit region 170 can be blocked by the frame portion 30a. As described above, since the peripheral circuit region 170 of the present embodiment is formed in the polysilicon layer formed on the substrate 16, the peripheral circuit region 170 is less affected by light and heat than that formed on the silicon substrate. Easy,
These tend to cause a leak current and the like. However, since the frame 30a of the spacer 30 is formed so as to shield light and heat from the backlight unit 40 to the peripheral circuit region 170 as described above, the light and heat reach the peripheral circuit region 170. It is possible to reduce the possibility that a leak current occurs.

The light guide plate fixing frame 56 has a bottom portion 57,
The light guide plate 44 is fixed from the back side. Light guide plate fixing frame 56

Are formed so as to come into contact with the end faces 47, 47, 46 of the light guide plate 44, whereby the light guide plate 44 is
7 and is positioned at a predetermined position in a plane substantially parallel to 7. Therefore, the light guide plate 44 and the light guide plate fixing frame 56 can be positioned with high accuracy with a short man-hour. In addition, since the positioning of the light guide plate 44 and the light guide plate fixing frame 56 can be performed without using a double-sided tape or the like, the frame area which cannot be used as a light emitting surface due to the attachment of the double-sided tape or the like, and the outer shape increases. The weight and thickness do not increase due to the double-sided tape or the like.

The plurality of positioning portions 58 are provided on the light guide plate 4.
Of the end faces 4 where the fluorescent tube 50 is not disposed
7, 47, and 46 are formed in a planar shape that almost covers them in close contact with each other. In addition, the positioning portions 58, 58, 5
8 are formed with sufficient reflectivity, so that the positioning portions 58, 58, 58
Thus, the efficiency of using light from the fluorescent tube 50 can be improved.

The reflector 66 covers the periphery of the fluorescent tube 50 except for the side of the light guide plate 44, and reflects light from the fluorescent tube 50 toward the light guide plate 44.

The shield case 72 houses an inverter (not shown), which is a power supply for generating a predetermined voltage supplied to the fluorescent tube 50, and the like.

As described above, in the liquid crystal display device 10 of the present embodiment, the sealing portion 22 formed by closing the liquid crystal injection port 80 is located at the position where the end surfaces of the active matrix substrate 15 and the counter substrate 24 are shifted. Non-facing region 144
Is provided on one side. Moreover, the sealing portion 22
One side does not protrude from the end surface of the active matrix substrate 15. Therefore, the sealing portion 22 protrudes from the end face of the liquid crystal panel 14, and the liquid crystal display device 1
The frame area of 0 does not increase. Also, the sealing portion 22
Of the liquid crystal display device 1
It is also unlikely that the reliability of 0 will decrease.

Further, in the liquid crystal display device 10, the terminal portion 81 is formed in the overhang region 140 of the active matrix substrate 15, and the sealing portion 22 formed by closing the liquid crystal injection port 80 is formed on the side corresponding to the overhang region 140. Since the liquid crystal injection port 80 is formed on one side other than the
1 is provided on a different side. Therefore, when filling the liquid crystal from the liquid crystal injection port 80, the terminal 81
Contamination can be easily avoided, and the liquid crystal terminals 8
It is unlikely that an increase in electric resistance and a decrease in reliability in the electrical connection of the terminal portion 81 due to the contamination 1 occur.

1.2 Liquid Crystal Panel FIG. 2 shows a liquid crystal panel 1 as a display panel of the present embodiment.
FIG. 4 is a plan view of FIG. FIG. 4 is a partial cross-sectional view showing details in the vicinity of an end of the liquid crystal panel 14 (position along the line HI shown in FIG. 2).

As shown in these figures, the liquid crystal panel 14
Is an active matrix substrate 15 as a first substrate
And a counter substrate 24 as a second substrate, and a liquid crystal 86 sealed and sandwiched between these substrates. The active matrix substrate 15 is formed by depositing ITO on the surface of a substrate 16 made of quartz glass or heat-resistant glass.
(Indium Tin Oxide) pixel electrodes 17 are formed in a matrix. The counter substrate 24 is
Substrate 2 also made of quartz glass or heat-resistant glass
5 is provided with a counter electrode 26 provided on the surface thereof.
Further, in the active matrix substrate 15, the substrate 16
A light-shielding film 19 is formed in advance on the lower surface of the surface where the pixel-switching TFT 18 is formed. After the protective film 20 is formed on the surface, T
An FT 18 and a pixel electrode 17 are formed, and their surfaces are covered with an alignment film 21. When color display is performed using the liquid crystal panel 14, a color filter is formed in a region of the counter substrate 24 facing each pixel.

In the active matrix substrate 15, a region located around a display region including the pixel electrode 17, the TFT 18, and the like is a peripheral circuit region 170. Then, in the peripheral circuit area 170, the driving circuit TFT formed simultaneously with the pixel switching TFT 18 is formed.
(Not shown) scanning line driving circuit 171
And a data line driving circuit 174 are formed. In the active matrix substrate 15, the peripheral circuit region 170 and the display region 130 are formed in a facing region facing the facing substrate 24. Further, the terminal portion 81 formed at the end of the active matrix substrate 15 is located in a region protruding from the counter substrate 24, that is, in an overhang region 140. The active matrix substrate 15 has the overhang region 1
Except for 40 and the non-facing region 144, the planar shape is substantially the same as the facing substrate 24.

The opposing substrate 24 includes a light-shielding film 27 for shielding a region inside the formation region of the sealing material 76 and outside the display region 130, and the active matrix substrate 1.
A light-shielding film 28 is formed to shield an area corresponding to a boundary area between the pixel electrodes 17 of FIG. An opposing electrode 26 is formed on the surface side of these light shielding films 27 and 28, and an alignment film 29 is formed to cover the opposing electrode 26.

The active matrix substrate 15 and the opposing substrate 24 are maintained at a predetermined interval by a gap material (not shown) dispersedly arranged therebetween, and a seal disposed at a position along the periphery of the opposing substrate 24. They are attached by a material 76. In this way, the liquid crystal 86 as an electro-optical material is sealed in a region defined by the active matrix substrate 15, the counter substrate 24, and the seal member 76.

Further, as shown in FIG.
Are partially interrupted at a position facing the non-opposing region 144, and the interrupted portion is a liquid crystal injection port 80. For this reason, after the opposing substrate 24 and the active matrix substrate 15 are bonded to each other, the inner region of the sealing material 76 is decompressed, so that the liquid crystal injection port 80 is formed.
The liquid crystal 86 can be injected under reduced pressure. After the liquid crystal 86 is injected, the liquid crystal injection port 80 is sealed by the sealing portion 22 made of resin.

As described above, since the liquid crystal injection port 80 is provided facing the non-opposing region 144 of the active matrix substrate 15, after the liquid crystal 86 is injected, the liquid crystal injection port 80 is formed.
Of the active matrix substrate 15 is also positioned facing the non-facing region 144 of the active matrix substrate 15. The sealing portion 22 is located inside the periphery of the active matrix substrate 15, and as shown in FIG. 5 which is a side view seen from the direction of arrow J shown in FIG. Although they protrude from the end surface 32 of the active matrix substrate 24, they do not protrude from the end surface of the active matrix substrate 14. As a result, the sealing portion 22 protrudes from the end face of the liquid crystal panel 14, and the frame area of the liquid crystal panel does not increase by the amount of the protrusion. Also, the sealing portion 22 may be damaged by interference with other members,
The possibility that the reliability of the liquid crystal panel 14 is reduced is low.

Further, the liquid crystal injection port 80 is provided on a side different from the side corresponding to the overhang region 140 where the terminal portion 81 is provided. Therefore, when the liquid crystal 86 is filled, contamination of the terminal portion 81 can be easily avoided, and
Due to the contamination of the terminal portion 81 by the liquid crystal 86, the terminal portion 81
It is unlikely that the electrical resistance and the reliability of the electrical connection will increase.

The liquid crystal panel 14 is formed on the light-incident side and the light-exiting side of the active matrix substrate 15 and the counter substrate 24 using a plastic sheet according to the normally white mode / normally black mode. Polarizing plates (polarizing sheets) 84 and 85 are arranged in a predetermined direction.

In the present embodiment, light is incident from the active matrix substrate 15 and is emitted from the counter substrate 24. On the contrary, light is incident from the counter substrate 24. May be incident and emitted from the active matrix substrate 15.

In the liquid crystal panel 14 configured as described above, on the active matrix substrate 15, the image signal applied to the pixel electrode 17 via the data line (not shown) and the TFT 18 causes the pixel electrode 17 and the counter electrode 26 to be connected to each other. During this period, the alignment state of the liquid crystal 86 is controlled for each pixel, and a predetermined image corresponding to the image signal is displayed. For example, when the liquid crystal panel 14 is configured in the TN mode, when the rubbing process is performed on the alignment films 21 and 29 formed between the pair of substrates (the active matrix substrate 15 and the counter substrate 24), the rubbing direction is changed. If the directions are set to be orthogonal to each other, the liquid crystal 86 is twisted and oriented at an angle of 90 ° between the substrates. Such a twist alignment causes the liquid crystal 8 between the substrates.
6 is released by applying an electric field. Therefore, depending on whether an external electric field is applied between the substrates,
The alignment state of the liquid crystal 86 can be controlled for each region (pixel) where the pixel electrode 17 is formed. Therefore, in the case of the transmissive liquid crystal panel 14, the light from the light source, that is, the light from the backlight unit 40 is adjusted to a predetermined linearly polarized light by the polarizing plate 84 on the incident side, and then is incident on the layer of the liquid crystal 86, so that a certain region is formed. The linearly polarized light that passes through is output while being rotated and the polarization plane is twisted, while the linearly polarized light that has passed through other regions is emitted without being rotated and the polarization plane is not twisted. Therefore, if the polarization plate 84 on the incident side and the polarization plate 85 on the emission side are arranged so that their transmission axes are orthogonal (normally white), the polarization plate 85 arranged on the emission side of the liquid crystal panel 14 can be obtained. Passes only linearly polarized light whose polarization plane is twisted by the liquid crystal 86. On the other hand, if the emission-side polarizing plate 85 is arranged so that the transmission axis is parallel to the incident-side polarization plate 84 (normally black), the polarizing plate arranged on the emission side of the liquid crystal panel 14 is provided. 85
Pass only linearly polarized light whose polarization plane is not twisted by the liquid crystal 86. Therefore, the liquid crystal 86
By controlling the alignment state of each pixel, arbitrary information can be displayed.
