かった。A display device using a TAB substrate includes at least a display panel, a TAB substrate on which an IC is mounted, and a peripheral circuit board for inputting signals to the TAB substrate. And TA
Conventionally, the B board and the peripheral circuit board are connected only by soldering the input signal terminals, and no other fixing method has been adopted.
TAB基板と周辺回路基板は、入力端子部のみで接続さ
れていたため、強度が非常に弱く、振動、落下等の外部
の力により、TAB基板の入力信号端子が破断するという
問題が発生しやすかった。Since the TAB board and the peripheral circuit board were connected only by the input terminal part, the strength was very weak, and the problem that the input signal terminal of the TAB board was easily broken by external force such as vibration or drop was likely to occur. .
本考案は、これらの問題点を解決するために、少なく

に、外部からの力が加わらない構造とした。In order to solve these problems, the present invention, at least in a display device including a display panel, a TAB board on which an IC is mounted, and a peripheral circuit board, has a hole at a position overlapping the peripheral circuit board of the TAB board. The peripheral circuit board is attached through the holes provided so that external force is not applied to the input signal terminals of the TAB board.
上記のような構成によれば、振動、落下等によるTAB
基板の入力信号端子切れという問題は解決された。According to the above configuration, TAB due to vibration, dropping, etc.
The problem of disconnection of input signal terminals on the board has been solved.
以下、本考案について実施例により詳細に説明する。 Hereinafter, the present invention will be described in detail with reference to embodiments.
