Claim Text:
1. A display control system comprising: a display panel that includes a pair of polarizing plates having transmission axes perpendicular to each other, the display panel being configured to display a visible image on a display surface thereof by using the pair of polarizing plates; a pattern layer that is disposed so as to overlap the display surface and has formed therein a plurality of patterns each representing information regarding a position on the display surface; a light source that emits light to be absorbed by the patterns, from a front side of the display panel; a reflector that is provided at a back side of the display panel and the pattern layer; an identification device that (i) reads the pattern from the light which is emitted from the light source, is reflected on the reflector, and then passes through the display panel and the pattern layer, and (ii) identifies a position, on the display surface, of the pattern; and a display controller that controls display information to be displayed on the display panel, in accordance with the position identified by the identification device, wherein a transmittance of the pair of polarizing plates at a peak wavelength of the light emitted from the light source is not lower than 70%.
