<p>PROBLEM TO BE SOLVED: To acquire excellent visibility by a simple circuit formation. SOLUTION: An ETC region 12A constituted from plural display pixels comprising LED, an intermediate region 12B and a general region 12C are formed on a display part 12, and package lighting control of each display pixel is executed in the display region unit corresponding to a toll receiving system of a lane by a control processing part 10 and a dimming part 11. The ETC region 12A is constituted from plural display pixels for displaying a purple base, and the general region 12C is constituted from plural display pixels for displaying a green base. The intermediate region 12B formed between the ETC region 12A and the general region 12C is constituted from the plural display pixels for displaying the purple base arranged on the ETC region 12A side and the display pixels for displaying the green base arranged on the general region 12C side across an inclined boundary part 12S.</p> |
