A method of the invention for forming a pixel-defining layer on an OLED panel is disclosed. The method of the invention for forming a pixel-defining layer on an OLED panel, comprising following steps: (A) providing a substrate; (B) forming a plurality of first electrodes in parallel stripes on said substrate; (C) coating a layer of non-photosensitive polyimide or polyimide precursor compositions on said substrate; (D) first prebaking said substrate; (E) coating a layer of photoresist compositions on said layer of non-photosensitive polyimide or polyimide precursor compositions; (F) second prebaking said substrate; (G) forming patterns of said photoresist by exposing said substrate to masked radiation and developing said photoresist; (H) etching said layer of said non-photosensitive polyimide or polyimide precursor compositions to form patterned polyimide or polyimide precursor compositions; (I) releasing or stripping said patterned layer of said photoresist compositions; and (J) baking said substrate with patterned non-photosensitive polyimide or polyimide precursor compositions to form said pixel-defining layer.
