A display device includes an insulating substrate, a thin-film transistor arranged on the insulating substrate, a pixel electrode including a transparent electrode, and an aluminum alloy film as a connection wiring section for electrically connecting between the thin-film transistor and the pixel electrode. Each prism is paired with one of the lenses. The data collected by one, or several, digital 3D360\xb0 camera systems can be used, to create a 3D model of a 360\xb0 scene by using triangulation of the image data within the overlapping fields of view. A laser is positioned to emit a laser beam onto a point on the burner head adjacent the conduit outlets and to heat that point to a temperature exceeding the ignition temperature of the fueloxidant mixture.
