Nowadays, mobile phones are very popular in the world. The use of text email with short message service (SMS) is spreading. In this study, we evaluated the legibility of characters on the liquid crystal displays of mobile phones. When characters are small, younger people assure readability by shortening the viewing distance. However, elderly people find it far more difficult to see small characters. Moreover, legibility deteriorates as the contrast of display becomes lower.
