In a light transmitting, color image display unit, a top surface of a black matrix partition wall exhibits lyophobicity relative to in-solution pigment particles while sidewall surfaces of the black matrix exhibit lyophilicity relative to in-solution pigment particles. This allows the pigment containing solutions to abut without repulsion against the sidewall surfaces. Consequently, it is possible to prevent color filter solutions deposited through an inkjet deposition process from overflowing over the lyophobic partition wall tops into adjacent pixel regions and it is also possible to conformably define color filters of consistent thickness between the black matrix partition walls.
