A liquid drop discharge device provides a head unit 420 which discharges
filter element material relative to each of various colors of color
filters. The head unit 420 is composed of an ink jet heads which are
arranged on one end of a print substrate plate having a shape of
rectangular card and head devices 433 which are arranged on the other end
of the print substrate plate comprising connectors 441. The head devices
433 are aligned in two rows, as two groups, in a staggered arrangement so
that a portion on which the connectors 441 are aligned in one of the two
rows does not face to the same portion of the other in the two rows and
protrudes outside of the print substrate plate. The head unit 420
discharges the filter element material onto predetermined portions in a
superimposing manner while shifting along a direction which intersects to
a direction along which the head devices 433 are arranged.
