NOVELTY - An X-ray imager comprises a substrate, an array of thin film transistors (TFTs) disposed on the substrate, an array of electrodes disposed on the first substrate, an organic photo-imageable insulating layer containing acrylic and an intermediate protective insulating layer.    USE - None given.    ADVANTAGE - The invention provides X-ray imagers or liquid crystal display having an increased pixel aperture ratio.    DETAILED DESCRIPTION - The X-ray imager comprises:    (a) a substrate (19);    (b) an array of thin film transistors (TFTs) disposed on the substrate;    (c) an array of electrodes (3) disposed on the first substrate;    (d) an organic photo-imageable insulating layer (33) containing acrylic and has a dielectric constant (epsilon) of less than 4; and    (e) an intermediate protective insulating layer (32) disposed between (b) and (d) to prevent (d) from directly contacting the semiconductor material in the channels of the TFTs.    The array of TFTs includes address lines and the electrodes overlap at least one of the address lines. The photo-imageable insulating layer and the intermediate protective layer include contact vias (35) bridging the communication of the electrodes and the TFTs.    INDEPENDENT CLAIMS are also included for:    (A) a liquid crystal display (LCD); and    (B) a TFT array structure comprising:    (a) an array of TFTs on a substrate;    (b) row and column address lines;    (c) organic photo-imageable acrylic-inclusive insulating means; and    (d) an intermediate protective insulating layer.    The LCD comprises:    (i) a first substrate;    (ii) a liquid crystal layer;    (iii) array of transparent pixel electrodes;    (iv) gate lines and TFT gate electrodes;    (v) a semiconductor layer;    (vi) a source and a drain electrode in each TFT area on the substrate;    (vii) drain lines connected to the drain electrodes;    (viii) transparent organic polymer photo-imageable insulating layer; and    (ix) an intermediate insulating layer (32).
