Abstract

We developed new material, modified polyimide (MPI) that functions as both an alignment layer for the liquid crystal (LC) and a planarization layer (called overcoat (OC) layer) covering color filter layer. This functioning organic layer is very important to reduce process step and a cost when manufacturing in-plane switching (IPS) and fringe-field switching (FFS) devices since on top substrate of both devices, the alignment layer is coated over the OC layer. The MPI showed excellent aligning capability and high transparency with moderate degree of planarization. In addition, the fabricated twisted nematic LC cell showed similar electro-optic characteristics to those with conventional polyimide.
