摘要:
A filter plate usable with an ink jet head, an ink jet head with the filter plate, and a method of fabricating the filter plate are provided. The filter plate includes a filter substrate having a filter hole region. Filter holes having angled line shapes extend through the filter substrate of the filter hole region. Each of the filter holes may include an upper filter hole formed to have a first angle with respect to the filter substrate at an upper portion of the filter substrate, and a lower filter hole formed at a lower portion of the filter substrate to be connected to the upper filter hole and having a second angle with respect to the filter substrate different from the first angle.
