Composite display unit and electric apparatus using this

A first display element (1) and a second display element (2) are superposed. A first display element (1) held between the first and second transparent substrates (11, 12) of the liquid crystal layer (18) of the liquid crystal panel (10), provided in the (11) side of the first transparent substrate, a reflective polarizer plate (3), and provided in the second display element (2) side polarizing plate (4) constituted. In the example shown in FIG. 1, the reflective polarizer (3) and the polarizing plate (4) to the first display element (1) and a second display element (2) common. Since the reflective polarizing plate (3) allows the light transmission of the vibration in a specific direction, while the vibration reflected in a direction intersecting with the particular direction of the light, so by the adhesive layer of the same refractive index, the liquid crystal panel is directly (10) engages.
