Abstract

In order to shield the light incident from the chip side surface or chip rear surface of a semiconductor chip that forms an LCD driver, a light-shielding film is formed over the chip side surface and chip rear surface of the semiconductor chip itself, not using a light-shielding tape that is a component separate from the semiconductor chip. Accordingly, the light-shielding tape as a separate component is not used, and hence the trouble that the light-shielding tape may protrude from the surface of a glass substrate whose thickness has been made small can be solved. As a result, the thinning of a liquid crystal display, and the subsequent thinning of the mobile phone in which the liquid crystal display is mounted can be promoted.
