Abstract: <P>PROBLEM TO BE SOLVED: To provide a manufacturing method for a transreflective color filter substrate capable of improving the efficiency of a production process and securing both of the brightness of a reflection type and the saturation of transmission type display.  <P>SOLUTION: The transreflective color filter substrate is provided with a transmission type color filter part and a reflection type color filter part for one pixel region. Light from a back light passes through a coloring layer once in a transmission mode and external light made incident on a display device is made to pass through the coloring layer twice by a reflector arranged in a lower layer in a reflection mode. Thus, by examining the color filter film thickness of a transmission region and a reflection region, the saturation and brightness of an electrooptical display device are improved. In this invention, by using a halftone mask, a color filter film thickness difference between the transmission region and the reflection region can be increased though the number of masks is same as before. Thus, a transreflective electrooptical device of high display quality is obtained without increasing processes.  <P>COPYRIGHT: (C)2004,JPO
