A color filter for an electronic display comprises a plurality of elongate filaments bonded together such that the longitudinal axes of the filaments are substantially coplanar. A method for making a color filter of short filaments comprises bonding the filaments into a ribbon, assembling these ribbons into a block and slicing thin layers from this block in a direction perpendicular to the filaments. A method for making a color filter of short filaments comprises casting a matrix around a plurality of spaced apart filaments, solidifying the matrix, and slicing the matrix and embedded filaments in a direction perpendicular to the filaments.
