Processes for preparing phosphor pattern, phosphor pattern prepared by the same and back plate for plasma display panel

摘要

Disclosed are a process for preparing a phosphor pattern of the present invention comprises the steps of: (I) forming a phosphor-containing photosensitive resin composition layer (A) on a substrate having unevenness, (II) irradiating a scattered light to the layer (A) imagewisely, (III) developing the layer (A) by removing the portion to which the scattered light is imagewisely irradiated to form a pattern, and (IV) calcinating the formed pattern to remove an unnecessary portion from the pattern formed in the step (III) to form a phosphor pattern, a phosphor pattern produced by the above process and a back plate for the plasma display panel provided with the phosphor pattern on a substrate for a plasma display panel.
