<p>Disclosed is an electronic device which is formed thin while maintaining good display by a liquid crystal display unit. Specifically disclosed is an electronic device wherein a main substrate (130) mounted with an electronic component is so arranged as to face a reflective sheet (126) which is formed on the back surface of a liquid crystal display unit (110). A flexible substrate (140) arranged between the liquid crystal display unit (110) and the main substrate (130) is connected to a surface (132) of the main substrate (130), which surface (132) is on the side of the reflective sheet (126). A protective sheet (150) covering the reflective sheet (126) is interposed between the flexible substrate (140) and the reflective sheet (126).</p>
