Abstract
A process for the manufacture of an electrooptical display device including a circuit board and a liquid crystal display cell mounted on the circuit board, including forming a circuit board having at least one light conducting region; disposing the liquid crystal display cell adjacent the light conducting region of the circuit board; locating at least one light emitting element in the circuit board for illuminating the light conducting region; and attaching a semi-transparent reflector to the liquid crystal cell; wherein at least part of the circuit board is manufactured by combining a reflecting layer, which is produced by the deposition of a reflective material on a substrate or on one side of a mesh, with a light diffusing substance, by embedding these two materials together in a transparent polyester or epoxy resin.
