Description
液晶表示装置1の構造について図4と図5に基づいて説明する。
次に、液晶表示装置1の製造方法について順番に説明する。
本実施形態によれば、光学フィルム20の角部に切り欠き部分6を設けることにより、対向基板14の角部が光学フィルム20によって覆われることがなく、液晶セル2の角部とバックライト3の角部との位置合わせを正確に行うことができる。そのため、液晶セル2とバックライト3とを組み合わせた場合に、光漏れなどが起こることがない。
上記実施形態では、長方形状の光学フィルム20の角部を一か所だけ切り欠いたが、より正確に位置合わせを行うために相対向する部分の角部や、隣接する角部に切り欠き部分6を設けて、複数箇所で位置合わせを行うようにしてもよい。
