Claim:
1. A plastic substrate, comprising: a plastic film, wherein the plastic film has a surface roughness of 2 μm or less; a conductive metal layer formed on and in contact with the plastic film, wherein the conductive metal layer has a thickness ranging from 1 to 50 nm; a passivation layer formed on the metal layer; and a resin layer having a conductive material dispersed therein formed on the passivation layer, wherein the resin layer has a thickness ranging from 10 nm to 2.5 μm, and wherein the resin layer includes 0.001-1 part by weight of carbon nanotubes based on 100 parts by weight of a solid content of the resin; wherein the plastic film, passivation layer and resin layer are formed from a polyimide varnish, being imidized, wherein the polyimide varnish have an average coefficient of linear thermal expansion (CTE) of 50.0 ppm/° C. or less when measured in a temperature range from 50° C. to 250° C. using a thermomechanical analyzer for a film thickness of 50-100 μm, with a yellowness index of 15 or less, and wherein the plastic substrate has a light transmittance of 50% or more at a wavelength of 500 nm and a surface resistivity of 2.5×10
