Method and apparatus for making a color filer are described in which substrates are subjected to uniform wet treatment without damaging the substrates. A liquid developer 3 is placed in a developing vessel 2 provided with a bubbler 4 at the bottom of the vessel 2. A plurality of glass substrates are vertically immersed in the developer 3 and bubbles 7 are generated by feeding N2 gas to the bubbler 4. The glass substrates 6 are developed while circulating the developer 3 by the bubbling.
