Problems solved by technology

Although such a transparent conductive film can be expected to have electromagnetic shielding effectiveness, it does not provide a solution to the problem of absorption of transmitted light at a specific wavelength depending on the light transmission spectrum of the metal, thereby causing discoloration of the conductive film and distortion of the transmitted image. Colors become unnatural and cannot be expected to provide sufficient anti-reflection performance

Abstract

A transparent conductive film according to the present invention has a transparent conductive layer containing at least two types of metals in a total amount of at least 10% by weight. This film is high in transparency, tonability, and conductivity, has exceptional static prevention and electromagnetic shielding effects, enables adjustment of the tone of transmitted images, and has exceptional durability with respect to saline resistance, acid resistance, oxidation resistance, and ultraviolet resistance. The low-reflectivity transparent conductive film of the present invention is provided with the above-mentioned transparent conductive layer 1, and at least one transparent thin film 2 having a refractive index different from the refractive index of the transparent conductive layer 1 above and/or below this transparent conductive layer. This film can be produced cheaply, is high in transparency, tonability, and conductivity, has exceptional static prevention and electromagnetic shielding effects, has exceptional anti-reflective effects, enables adjustment of the tone of transmitted images, and has exceptional durability with respect to saline resistance, acid resistance, oxidation resistance, and ultraviolet resistance. The display device of the present invention has the above-mentioned low-reflectivity transparent conductive film formed on the display screen thereof. This display device is high in transparency, tonability, and conductivity, has exceptional static prevention and electromagnetic shielding effects, has exceptional anti-reflective effects, enables adjustment of the tone of transmitted images, and has exceptional durability with respect to saline resistance, acid resistance, oxidation resistance, and ultraviolet resistance.

Description

[0001] This application is based on a divisional application filed on PCT application WO 97 / 48107 with a filing date of June 2, 1997. technical field [0002] The present invention relates to a paint for forming a transparent conductive layer capable of forming a transparent conductive layer, which has high transparency, colorability and conductivity, extremely high antistatic performance and electromagnetic shielding performance, and has greatly improved properties such as Durability in terms of salt resistance, acid resistance, oxidation resistance and UV resistance. Background technique [0003] Conventionally, transparent materials with high dielectric constants, such as glass and plastic, tend to accumulate static charges and allow transmission of electromagnetic waves. Especially on cathode ray tubes and plasma displays, which are often used in TV picture tubes and computer monitors, due to the static electricity generated on the display, dust will accumulate on it, re...
