ｍ布したものであることを特徴とする表示装置である。DETAILED DESCRIPTION OF THE INVENTION The invention relates to a display device having a novel transflective plate, which is described in more detail below. The liquid crystal display element is made by pasting a polarizing plate on one glass plate surface through a liquid crystal cell filled with Hatakemaki's Ic liquid crystal between glass plates, and attaching a polarizing plate to the other glass plate surface. It consists of a polarizing plate and a semi-transparent reflective plate that are sequentially attached to a glass plate surface.The semi-transparent reflective plate of a conventional liquid crystal display element has a polarizing plate and a semi-transparent reflective plate that are made of a transparent part and a light blocking part. In a display device in which a transmissive reflective plate and a light emitting part are located as essential components in the above order,
Transflective plates are made by vacuum-depositing aluminium, aluminum, etc. on the surface of a plastic film or matte-treated plastic film. The disadvantages are that the light becomes grayish and that it is difficult to adjust the reflectance and transmittance during manufacturing. Therefore, the present inventors have intensively studied methods to eliminate these disadvantages. The present invention has been achieved in which a transflective plate is manufactured by adding metal powder to a resin and applying the coating.In other words, the present invention is a display plate consisting of a light-transmitting part and a light-shielding part, and a transflective plate-light-emitting part. In the display device, which is positioned as an essential component in the above order, the scissors semi-transparent reflective plate transfers the metal powder onto the thin plate.
This is a display device characterized in that it is made of cloth.

れＥｌｌ定されない。In the above-mentioned transmission-reflection plate, metal powder is applied to a thin plate using a KIk cloth (KiK), metal powder is added to W resin (plastic film sheet), or a thin plate such as a glass plate is coated to achieve light transmission and reflection. #i It is preferable to provide adhesive performance at the same time. ◎ Conventionally used transflective plates are manufactured by vacuum-depositing aluminum, etc. on the surface of plastic film or matte-treated plastic film, but light transmission If the amount of aluminum evaporated is reduced in order to increase the ratio, the reflected light will be grayish and the display performance will deteriorate, but
In the display device of the present invention, clear reflected light can be obtained even if the light transmittance is increased, and clear pattern display can be achieved with pongee.
It is difficult to adjust the reflectance and transmittance of a semi-transparent reflector using the vacuum deposition method, and it is even more difficult to uniformly deposit the film over a wide range of films.However, in the present invention, it is possible to adjust the reflectance and transmittance by It is also easy to obtain it by uniformly distributing it on a 1/& film. Atasho, a manufacturer of semi-transparent reflectors, uses resin added with metal powder to produce plastic film surfaces.
It is also possible to apply an anchor coat to the plastic surface when applying mlk cloth.
It is also possible to coat resin with metal powder on the plastic surface aCi & cloth and then apply an adhesive and laminate it, but directly 11! The method of adding metal powder to the adhesive and applying it is good because the process can be omitted. Examples of thin plates to which metal powder is applied include glass plates, plastic films, sheets, etc. Examples of the sheet material include polyester film, melipeda pyrene film, polyvinyl chloride film, triacetate film, AC VK film, polystyrene film, polydecylaf zero-wire ethylene film, and sheets of these. Plastic films or sheets with surface matte processing or kneading matte processing can also be used. ◎Plastic film sheet The thickness of the sheet is 10~J
100μ is appropriate. The metal powder may be granular, but it depends on the use of scaly aluminum, gold, silver, copper, tin, Yuta Go, etc. with an average diameter of lO~1000μ.
The average diameter is large. ・Reflectance should be determined by taking into consideration the balance of transmittance as the amount of metal powder applied increases. Acrylic, polyester, dioxylic, urethane vinyl chloride/
Examples include vinyl acetate, natural rubber, and synthetic rubber, but acrylic with good transparency is preferred.Adhesive or non-adhesive products are selected depending on the purpose of use.As for the application method, Examples include gravure roll, reverse roll, plate rotor, and rod coater.・Coating thickness FisHi is determined by the balance between emissivity and transmittance, but I~100# is preferable, and Filo−40μ is appropriate.・The transmittance is preferably between 6.0 and 40 to 80 degrees. ◎ It is also possible to improve the smoothness of the metal powder by compressing it with a pressure roll after coating and drying. ◎ In the present invention A typical example of the liquid crystal display panel is a light shielding plate having a transparent hole, or a light shielding plate having a transparent hole.A typical example of the liquid crystal display panel section is one in which polarizing plates are installed on both sides of a liquid crystal cell, but this is not specified.

龜る。The display device of the present invention has the advantage of using a semi-transparent reflector plate which has good uniformity and imparts reflective/transmissive functions and adhesive properties at the same time.Also, this display device company uses a polarizing film instead of a plastic film. In particular, it is possible to manufacture polarizing plates/semi-transmissive reflectors for use in LCD displays in one process.Furthermore, if necessary, semi-transmissive reflectors can be manufactured by applying metal powder to the surface of the lighting device. It also slows down.
