A wiring substrate is arranged so that a first periphery electric wiring and a
second periphery electric wiring are patterned on an active matrix substrate, and
a TCP as a electronic component is provided on a portion of the patterned electric
wiring. The first periphery electric wiring and the second periphery electric wiring
are formed by including a metal thin film and a transferred metal film. Further,
in the portion where the TCP is provided, the first periphery electric wiring and
the second periphery electric wiring either have a monolayer structure with one
of the metal thin film and the transferred metal film, or have a lamination structure
with both of the metal thin film and the transferred metal film. On this account,
connection failure can be prevented on a low resistance wiring substrate.
