Description
次いで、画素部の周辺(外側)の領域に、画素部へ各信号を伝送する駆動回路が形成されたデータ線側IC406、走査線側IC407をCOG方式によりそれぞれ実装する。COG方式以外の実装技術としてTCPやワイヤボンディング方式を用いて実装してもよい。TCPはTABテープにICを実装したものであり、TABテープを素子形成基板上の配線に接続してICを実装する。データ線側IC406、および走査線側IC407は、シリコン基板を用いたものであってもよいし、ガラス基板、石英基板もしくはプラスチック基板上にTFTで駆動回路を形成したものであってもよい。また、片側に一つのICを設けた例を示しているが、片側に複数個に分割して設けても構わない。
