<P>PROBLEM TO BE SOLVED: To provide a projection type display device and an optical unit capable of effectively eliminating uneven hue due to in-plane variations in the thickness of liquid crystal layers in a plurality of liquid crystal panels corresponding to the respective wavelength ranges. <P>SOLUTION: The projection type display device includes three reflective liquid crystal panels 100 (a red liquid crystal panel 100R, a green liquid crystal panel 100G, and a blue liquid crystal panel 100B) to which light beams of the respective colors are incident. The film thickness of an ITO film constituting a common electrode 21 in the blue liquid crystal panel 100B is smaller compared to the film thickness of an ITO film constituting a common electrode 21 in the red liquid crystal panel 100R and in the green liquid crystal panel 100G. The film thickness of the ITO film constituting the common electrode 21 is the same in the red liquid crystal panel 100R and in the green liquid crystal panel 100G. <P>COPYRIGHT: (C)2012,JPO&INPIT |
