We developed two new polarizer system. One system realizes an 17% increase in on-axis contrast. Another realizes an 8% increase in on-axis brightness and on-axis contrast. Moreover, we improved color shift at deep polar angle by optimizing the design of additional retarder. These effects are achieved by suppressing unwanted oblique light by simply changing film configuration of bottom polarizer. These technologies can be easily introduced.
