<p>A touch panel (100) is constructed of a top sheet member (110) having a resistive membrane (111) on its inner surface and a base sheet member (130) having a resistive membrane (131) on its inner surface, the top and base sheet members facing each other with dot spacers (160) being located in between. The top sheet member is formed by laminating a PET film (101), a polarizing film (102), a 1/4 lambda retardation film (103), and a light isotropic (104) film in this order from its outer surface. The PET film has a thermal expansion coefficient lower than the other films underneath, such as the polarizing film. Accordingly, the PET film serves to keep the other films of the top sheet member from bulging outward when the temperature rises. <IMAGE></p> |
