发明名称 DISPLAY DEVICE
摘要 <P>PROBLEM TO BE SOLVED: To provide a display device with a high contrast ratio, and to manufacture such a high-performance display device at low cost. <P>SOLUTION: In a display device having a display element interposed between a pair of light-transmitting substrates, a stack of polarizer-including layers in a parallel nicol state is provided outside each of the light-transmitting substrates. Here, transmission axes of polarizers that are stacked in the stack on one side of the display element and transmission axes of polarizers that are stacked in the stack on another side of the display element are arranged to be displaced from a cross nicol state. Also, a retardation film may be provided between the polarizers that are stacked and the substrate. <P>COPYRIGHT: (C)2008,JPO&INPIT
