Abstract
Description
上記した特許文献1によれば、液晶パネルを小さくでき、且つ、表示領域を大きくできるようになっている。しかしながら、例えば表示画像の高精細化が進行し、表示領域内の配線数が増加すると、基板上の端子部の形成範囲が広くなるとともに端子部に接続されるフレキシブル基板の幅も広いものとなる。端子部の形成範囲及びそこに接続されるフレキシブル基板の幅が広くなると、それに応じて第2領域を拡張する必要が生じるため、それに伴って基板の最大外径を大型化せざるを得ない。ここで、仮に液晶表示装置全体の外形を基板の外形に倣う形態とすると、液晶表示装置の筐体などの形状が複雑化することから、液晶表示装置の外形を単純な円形にするのが好ましい場合がある。ところが、その場合には、液晶表示装置の径寸法を、液晶パネルの基板の最大外径と等しくなる設定とせざるを得ないため、液晶表示装置の額縁幅を広くせざるを得なくなるとともに液晶表示装置の外形が大型化せざるを得なくなっていた。
本発明の表示装置は、実質的に円形または楕円形とされる外周縁部を部分的に直線状にしてなる直線状縁部が複数設けられる表示パネルと、前記表示パネルの外周側部分にて周方向について複数の前記直線状縁部の配置と整合する形で実装される複数の実装部品と、を備える。

本発明によれば、狭額縁化を図るとともに大型化を抑制することができる。
