Description

594062 A7 _ B7 V. Description of the invention (1) (Background of the invention) Technical field of the invention The present invention relates to color filters, especially those of reflective or transflective liquid crystal display devices. 2. Description of the Related Art In recent years, the use of a color liquid crystal display device as a flat display has been ordered. This color liquid crystal display device can be classified into a reflective type and a transmissive type. A reflective color liquid crystal display device, for example, has a colored layer made of a plurality of colors (usually three primary colors of red (R), green (G), and blue (B)) (if necessary, it also has a black matrix or flattening) Layer) and color electrode with transparent electrode layer, reflective electrode layer made of metal such as aluminum and thin TFT array substrate of film transistor (TFT element), with specified gap and alignment, so that A liquid crystal layer is formed on the gap portion, and a phase difference plate, a polarizing plate, and a front scattering plate are provided on the color filter (observer side). The aforementioned front-scattering plate has a light-scattering function, and is provided for appropriately scattering light that has been incident on the reflective liquid crystal display device and ensuring sufficient visibility. However, in the conventional reflective color liquid crystal display device, the presence of a front scattering plate causes a problem that the brightness of the liquid crystal display device is lowered and the color characteristics are lowered. This is caused by the color attached to the front diffuser. In addition, due to the presence of the front scattering plate, there are also problems with parallax (image blur). The above-mentioned decrease in brightness is due to the conventional reflective color liquid crystal display device equipped with a front scattering plate on the color filter (observer side). This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm). 7 ^ " " ~ (Please read the notes on the back before filling in this page), 11 · Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs 594062 A7 B7 Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs SUMMARY OF THE INVENTION (2) Inevitable problems. To solve such a problem, by including light-scattering microparticles in the color filter, imparting light-scattering property to the color filter itself is considered as a proposal. This makes the front scattering plate unnecessary, so that it is possible to solve the above-mentioned problems accompanying the front scattering plate to some extent. However, when a sufficient light-scattering function is to be imparted by the light-scattering fine particles, the light-scattering layer may become a thick film as a result. For example, the thickness of a common protective film is less than 2 // m, but the light scattering function film can also have a thickness of about 0.5 to 2 0 // m. At this time, if there is too little coloring component in the composition forming each layer, if there is a coloring component that adversely affects the color characteristics of the color filter, the thicker the film, the more this coloring phenomenon is emphasized. Here, as for the coloring component, it can be regarded as a resin component, a polymerization initiator, etc., and these are not limited to a thermosetting type or a photocuring type, and it is known to have a color ranging from light yellow to red. Summary of the Invention The present invention has been made in view of the above-mentioned facts, so as to provide a color that eliminates the need for a front scattering plate, and has high brightness and no parallax (image blur), prevents deterioration of color characteristics, and achieves excellent color characteristics. Filter for the purpose. In order to achieve such an object, the present invention is a color filter including at least a coloring layer composed of a substrate and a coloring pattern of a plurality of colors, and a coloring material for containing light-scattering fine particles and correcting color characteristics. It becomes a characteristic color filter. (Please read the notes on the back before filling this page)

Color Filters of the First to Sixth Aspects The color filters of the sixth aspect to the sixth aspect of the present invention are those in which the printed particles of the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs of the Ministry of Light Scattering contain the color filters. It's just a state in one layer. Among these aspects, the color filters of the first to third aspects are color filters of the type arranged on the observer's side for the liquid crystal layer in the reflective color liquid crystal display device. In the fourth to sixth aspects of the color filter, the liquid crystal layer is arranged in the reflective color liquid crystal display device on the observer side and the opposite side. The first aspect of the color matte film is applicable to the Chinese National Standard (CNS) A4 specification (210X297 mm) -15- 594062 A7 B7 V. Description of the invention (13) Figure 1 shows the first aspect of the invention A schematic longitudinal sectional view of a sample color filter. The color filter 1 shown in FIG. 1 has a transparent substrate (please read the precautions on the back before filling this page) 2. The light scattering layer 3 provided on this transparent substrate 2 is pre-laminated on the light The colored layer 4 and the transparent electrode layer 5 on the scattering layer 3, and the colored layer 4 are composed of a red colored pattern 4 R, a green colored pattern 4 G, and a blue colored pattern 4 B. As for the transparent substrate 2 constituting the above-mentioned color filter, quartz glass, Pyrex glass, synthetic quartz plate and other non-flexible transparent hard materials, or transparent resin films, optical resin plates, etc. can be used. Transparent soft material. The scattering layer 3 constituting the color filter 1 is one that appropriately diffuses the light that has been incident on the reflective liquid crystal display device and ensures sufficient visibility, and disperses the light-scattering fine particles in the translucent resin. Examples of the translucent resin include acrylic resin, epoxy resin, polyvinyl alcohol resin, polyimide resin, and polyvinyl ether resin.

Printed by the Consumer Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs As for the light-scattering particles, the ones listed in (c) above can be used. The content of the fine particles of the light scattering layer 3 is 0.5 to 70% by weight, preferably in a range of 1.0 to 50% by weight, and the thickness of the light scattering layer 3 is 0.5 to 20 # m, preferably 1.0 to l0 // m degree. Here, it is necessary to make the intensity of the scattered light caused by the light scattering layer 3 sufficient, and it is necessary to increase the haze (昙 fog 値 = [diffused light transmittance) / (total light transmittance) X 1 0 0].

Description of the invention (14) (Please read the precautions on the back before filling This page)) is possible, and it is necessary to increase the particle concentration or the thickness of the light scattering layer, but at this time, it is not appropriate that the total light transmittance and the diffused light transmittance are reduced. For example, when a known titanium dioxide or calcium carbonate is used as a general fine particle, if the concentration of the fine particle or the thickness of the light-scattering layer is increased, the light-shielding property of the particle will appear, and the total light transmittance will be significantly reduced. In the color filter 1 of the present invention, by using the fine particles used in the light scattering layer 3 as the above-mentioned material, the mist can be set to 10 to 90, preferably 25 to 80, and more preferably 3 to 7 In the range of 0, the total light transmittance is set to 30% or more, and the diffuse light transmittance is set to 10% or more.

The thickness of such a transparent electrode layer 5 is 0 · 01 to 1 // m, and preferably 0 · 03 to 0.5 // m degree. This type of color filter 1 can reliably prevent the coloring of the light scattering layer 3 by correcting the color characteristics caused by the color material. Therefore, the reflection type color liquid crystal display device manufactured by using the color calender 1 and other steps has almost no effect.
