Patent ID: 7884537

Claim:
A pattern substrate comprising: a substrate; and a conductive pattern disposed on the substrate wherein said conductive pattern is formed to include two or more overlapping circular patterns by discharging liquid drops including particles of a conductive material and formed in a line-shaped pattern, wherein a plurality of bar-shaped patterns are disposed outside a region of the conductive pattern on the substrate, the bar-shaped patterns being formed by discharging liquid drops with the same liquid to form said conductive pattern, wherein said substrate has a smoothness that can obtain a clear dot pattern, and wherein the substrate has a first surface, side surfaces perpendicular to the first surface, and edges between the side surfaces and the first surface, the conductive pattern is formed on the first surface, the edges are chamfered, and the chamfered surface has a surface roughness ranging from 0.5 μm to 5 μm.
