In the case where input terminals of a display driver circuit are compatible with two or more types of interface specifications, an LSI chip, which is the display driver circuit, has some input terminals connected to parallel data lines and its output terminals connected to display lines, and these input terminals and output terminals are arranged along a long side located on the display portion side. In at least one example embodiment, the rest of the input terminals, which are intended for parallel interface, are arranged along a long side located on the FPC board side. With this configuration, the long sides of the LSI chip can be rendered shorter (than in the case where all input terminals are arranged in a row) without causing malfunction.
