Abstract
On a glass substrate of a liquid crystal display device, electrode parts to which metallic electrodes (bumps) of an IC circuit are connected from an upper part are formed. The electrode parts are formed by opening an interlayer dielectric film at parts corresponding to metal wiring and forming land shaped electrode pads in the opening parts. In this invention, the planar forms of the electrode pads are smaller than the opening parts of the interlayer dielectric film. Thus, the planarization of the peripheral surfaces around the electrode parts is improved. Accordingly, integrated circuit devices (IC) or semiconductor chips can be connected with high reliability.
