A driving element is provided to the liquid crystal display panel having the above structure to form a liquid crystal display device as shown in FIGS.

According to the liquid crystal display device shown in FIG. 4, the liquid crystal display device is composed of a film or the like on which drive elements having both segment side and common side output functions are mounted, that is, TCP (Tape Career Package) or FPC ( A flexible printed circuit board) is pressure-bonded to the connection terminal group via an anisotropic conductive film or the like.

Thus, according to the liquid crystal display device of the present invention,
Since the first output wiring 8 and the second output wiring 9 are connected in parallel, the resistance value of the output wiring portion can be almost halved as compared with the conventional one, and thus the maximum resistance of the output wiring portion can be made as compared with the conventional one. The value and the difference between the maximum resistance value and the minimum resistance value are halved, and the resistance value adjustment for eliminating display unevenness becomes easier and the display quality of the panel is improved.

Further in accordance with the present invention, resistance adjustment is typically

The present invention is not limited to the above embodiment, and various modifications and improvements can be made without departing from the scope of the present invention. For example, in the above embodiment, the second output wirings 9 are provided for all the first output wirings 8. However, the second output wirings are provided only for the patterns having a long wiring length (the wiring resistance value is high), and the wiring lengths are set. The resistance value may be adjusted by using only the first output wiring for a pattern having a short length (low wiring resistance value).

Next, a detailed configuration example of the liquid crystal display panel and the liquid crystal display device of the present invention, and a configuration example of the portable terminal or the display device will be described.

Specific Configuration Example of Liquid Crystal Display Panel A case of a transflective liquid crystal display device will be described with reference to FIG.

On the outer surface of the glass substrate 2, a retardation plate 16 made of polycarbonate or the like and an iodine type polarizing plate 17 are sequentially stacked, and on the outer surface of the glass substrate 1, a retardation plate 18 made of polycarbonate or the like and an iodine type polarizing plate. The boards 19 are sequentially stacked. These are attached using an adhesive material made of an acrylic material.

Further, in the figure, a backlight 20 is arranged below the polarizing plate 19. The backlight 20 is the light guide plate 2.
A light source 22 such as a cold cathode tube or an LED is arranged on the end face of 1,
The light emitted from the light source 22 is introduced into the light guide plate 21, and the light guide plate 2
The light is emitted to the liquid crystal display panel from 1.

In the liquid crystal display panel, the glass substrate 2
A segment electrode 4 and an alignment film (not shown) made of a polyimide resin rubbed in a certain direction are sequentially formed on the top. In addition, S is provided between the segment electrode 4 and the alignment film.
An insulating layer made of iO ₂ or the like may be interposed.

A semi-transmissive film 23 is formed on the inner surface of the glass substrate 1, and a color filter 24 is provided on the semi-transmissive film 23. Further, between the color filters 24, a thin film made of a metal such as aluminum or chromium or a black matrix which is a light shielding film formed of a photosensitive resist may be formed.

Then, SiO is formed on the color filter 24.
₂ or an overcoat layer 25 made of resin, a common electrode 3 on the overcoat layer 25, and an alignment film made of polyimide resin rubbed in a certain direction (not shown)
And are sequentially formed. The common electrode 3 is orthogonal to the segment electrode 4. An insulating layer made of SiO ₂ or the like may be provided between the common electrode 3 and the alignment film.

The semi-transmissive film 23 has both light transmissive and light reflective properties, and further, prevents the phase difference from occurring when sandwiched between two polarizing plates. Further, the semi-transmissive film 23 may have a specular property or a scattering property.
In order to manufacture the semi-transmissive film 23 having a scattering property, a resin may be used to form an uneven shape, and the semi-transmissive film may be formed thereon.

The color filter 24 is a pigment dispersion type,
That is, a photoconductor resist prepared in advance with pigments (red, green, blue, etc.) is applied on a substrate and formed by photolithography.

The glass substrates 1 and 2 thus formed are bonded together by the sealing material 5 via the liquid crystal layer 26 made of chiral nematic liquid crystal twisted at an angle of, for example, 200 to 270 °. Furthermore, both glass substrates 1, 2
A large number of spacers 27 are arranged between the two in order to keep the thickness of the liquid crystal layer 26 constant.

In the liquid crystal display device having the semi-transmissive film 23 arranged as described above, when it is used as a reflection type (reflection mode), irradiation light from external illumination such as sunlight or a fluorescent lamp is not generated. The light that has passed through the polarizing plate 17, the retardation plate 16 and the liquid crystal panel in this order passes through the color filter 24, reaches the semi-transmissive film 23, and is reflected by the semi-transmissive film 23. , Passes through the liquid crystal panel, passes through the phase difference plate 16 and the polarizing plate 17, and is emitted.

On the other hand, when the liquid crystal display device is set to the transmissive mode, the irradiation light of the backlight 20 sequentially passes through the polarizing plate 19, the retardation plate 18 and the glass substrate 1 of the liquid crystal panel to form a semi-transmissive film. 23, the color filter 24, the liquid crystal panel, the retardation plate 16 and the polarizing plate 1.
Light is emitted after passing through 7.

Further, by forming the semi-transmissive film 23 on the glass substrate 1, in the reflection mode, by increasing the reflectance in particular, a display of brighter brightness can be obtained and a high contrast can be obtained also in the transmission mode. It is possible to enhance both the reflective mode and transmissive mode functions to the extent that it can be satisfied, and the panel used in the reflective mode can be used in the transmissive mode under the same conditions. In any case, stable and clear color display was possible.

On the inner surface of the glass substrate 1, the semi-transmissive film 2 is formed.
Forming No. 3 prevents the glass substrate 1 from passing through even when it is used in the reflection mode, so that the reduction in double display of the display due to the glass substrate 1 does not occur. Further, since the incident light and the reflected light pass through the same pixel, it is possible to prevent deterioration of brightness and color purity.

The semi-transmissive film 23 is made of a metal thin film such as aluminum, chromium, SUS, aluminum alloy, silver alloy, or the like. However, as the film thickness increases, the light transmittance decreases and the light reflectivity decreases. growing. The thickness of such a metal thin film has a different light absorption coefficient depending on the type of metal, and is also defined by which of the two applications, reflection mode and transmission mode, the performance of which is required to be improved. However, it is usually 50 to 500Å, preferably 100 to 400Å. As a result, the characteristics of a semi-transmissive liquid crystal display device having a reflectance of 30 to 70% and a transmittance of 5 to 50% can be obtained.

For example, when the semi-transmissive film 23 is formed of an aluminum metal thin film having a film thickness of 250 Å, the reflectance is 6
The transmittance is 5% and the transmittance is 15%. In addition, this semipermeable membrane 23
May be made of a dielectric material to have a laminated structure of a low refractive index layer and a high refractive index layer.

Then, for the liquid crystal display device having the above configuration,
When the semi-transmissive film 23 is specular, a light-scattering plate may be further formed between the glass substrate 2 of the liquid crystal panel and the retardation plate 16. The light-scattering plate-like body may be, for example, IDS (Internal Diffusing S) manufactured by Dai Nippon Printing Co., Ltd.
There is a light-scattering film of eet), and beads and the like are contained in the resin. In addition, unevenness having light-scattering property may be provided on the surface of the flat plate. By providing such a light-scattering film between the liquid crystal panel and the retardation plate 16, when used as a reflection mode, the reflected light reflected by the semi-transmissive film 23 is not reflected by the light-scattering film except in the regular reflection direction. Scattered also in the direction of, which widens the viewing angle of the image display and widens the recognition area of the image display.

In the liquid crystal display device having the above-described structure, the semi-transmissive film 23 is provided to form a semi-transmissive liquid crystal display device. Instead of this, for example, aluminum metal, silver metal, aluminum alloy is used. Alternatively, a reflective liquid crystal display device may be provided in which a reflective film made of silver alloy or the like and only required to have light reflectivity is provided. In that case, the phase difference plate 1
8 and the polarizing plate 19 and the backlight 20 are unnecessary.

According to the present mobile phone, the liquid crystal display device of the present invention is arranged in the small casing 28. Further, an antenna 29 for transmission / reception is provided on the top of the housing 28, and a receiver 30 and a microphone 31 are further formed on the surface.
