従来より、液晶表示パネルを備えた表示装置が種々提案されており、例えば特許文献１に開示されている。斯かる表示装置の液晶表示パネルは、数字表示部及び環状のバーグラフを有するものである。数字表示部は、４組の日字形に配設されたセグメントからなるものであり、４桁の数字により物理量（例えば、エンジンの回転数）を表示する。バーグラフは列状に配設された多数のセグメントからなるものであり、数字表示部と同一の物理量を表示する。液晶表示パネルはネガ表示型またはポジ表示型となっており、バーグラフは物理量に応じた個数のセグメントを透過状態または不透過状態とすることにより前記物理量を表示する。
特開平１１−１１９６９５号公報 Conventionally, various display devices including a liquid crystal display panel have been proposed, and for example, disclosed in Patent Document 1. The liquid crystal display panel of such a display device has a numeric display section and a ring bar graph. The number display unit is composed of four groups of segments arranged in a letter shape, and displays a physical quantity (for example, engine speed) by a 4-digit number. The bar graph is composed of a large number of segments arranged in a row, and displays the same physical quantity as that of the numeric display unit. The liquid crystal display panel is of a negative display type or a positive display type, and the bar graph displays the physical quantity by setting the number of segments according to the physical quantity to a transmission state or a non-transmission state.
