According to one embodiment, a display device includes a display panel, switching elements, a power supply, a controller and a noise suppression circuit. The display panel displays an image. The switching elements supply a pixel signal to the display panel. The power supply supplies a power source voltage to the switching elements. The controller switches between a display period during which the display panel displays an image and a non-display period during which the display panel does not display an image. The noise suppression circuit preliminarily reduces a potential difference between the switching elements and the power supply when the controller switches between the display period and the non-display period.

Display device

A method of dividing a circuit pattern for creating complementary stencil masks corresponding to complementary patterns, the method comprising a step of dividing a circuit pattern into a plurality of complementary patterns including a first complementary pattern comprising a pattern of a cantilevered beam member having a support portion width Wand a length L, and a second complementary pattern comprising a pattern of a both end-supported beam member having a support portion width Wand a length L. The dividing of the circuit pattern is performed in a manner that a aspect ratio A(L/W) of the pattern of the cantilevered beam member is confined to not more than 100, and that a aspect ratio A(L/W) of the pattern of the both end-supported beam member is confined to not more than 150.
