The present invention provides an image display device in which peripheral circuits including a D/A converter are integrated on a glass substrate while realizing high-precision image display. An image display device of the invention has a display area (100) constructed by a plurality of pixels (1). Serial data and commands input from signal lines (s1 and s2) are input to a buffer circuit (10) via an interface circuit (14) and a D/A converter (11). An output of the buffer circuit is input to the horizontal shift register (13) and sequentially scanned and written to the signal line 2. A vertical shift register 8 switches a pixel switch 4 of a pixel to which the image signal is to be written to the on state via a gate line 3, and the pixel displays the optical characteristics according to the written image signal. A buffer circuit made of single crystal Si and a supply voltage-generating circuit (32) for the buffer circuit are provided on an FPC, and other circuits made of polycrystalline Si are provided on the glass substrate 6.
