Process and materials are described for selectively placing uniform spacers on a receptor. Spacer elements are placed on a receptor by selectively irradiating a thermal transfer donor sheet comprising a transferable spacer layer. The transferable spacer layer may include particles or fibers to form a composite. The particles may have a spacing dimension either greater than or less than the thickness of the transferable layer. When the spacing dimension of the particle is greater than the thickness of the transferable layer, then the spacing dimension of the particles control the spacing distance. The process and materials are useful in the manufacture of flat panel displays, particularly, liquid crystal display devices.

[ What is claimed:] [1.] A process for selectively placing spacers on a receptor for use in a flat panel display comprising the steps of:(i) providing a receptor and a thermal transfer donor sheet, said donor sheet comprising in order,(a) a support,(b) a transferable spacer layer, and(c) an optional adhesive layer, rein at least one of said receptor, said support, said spacer layer or said optional adhesive layer comprises a radiation absorber;(ii) placing in intimate contact said receptor with said transferable spacer layer of said thermal transfer donor sheet;(iii) irradiating at least one of said thermal transfer donor sheet or said receptor in an imagewise pattern with imaging radiation, said imaging radiation being absorbed by said radiation absorber and converted to sufficient heat to transfer irradiated areas of said transferable spacer layer of said thermal transfer donor sheet to said receptor;(iv) transferring said transferable spacer layer in said irradiated areas to said receptor; and(v) removing said thermal transfer donor sheet to form spacer elements corresponding to said irradiated areas on said receptor.
