A display device displays a plurality of display elements having respective densities that continuously change in a first direction (an X direction), in such an arrangement that the display elements constitute a pointer needle and the densities continuously change in a second direction (a Y direction) intersecting the first direction, thereby displaying the pointer needle on a display section. This provides a display device with improved stereoscopic vision of the pointer needle.

A Bourdon tube pressure gauge includes: a Bourdon tube; a rotary piece rotatably attached to a first shaft arranged near a tip of the Bourdon tube; a pointer including a second shaft arranged on a side facing an outer periphery of the fan-shaped portion of the rotary piece; a first permanent magnet provided on an outer peripheral surface side of a fan-shaped portion of the rotary piece; a second permanent magnet provided at the second shaft. An outer peripheral surface of the first permanent magnet and an outer peripheral surface of the second permanent magnet each has N pole and S pole alternately magnetized at equal pitches. A magnetic member configured to relax force by which the second permanent magnet is attracted to the first permanent magnet is provided across the second permanent magnet from the first permanent magnet.

A display device includes a dial, a substrate, a plurality of light source parts, and a transmittance adjustment part. The transmittance adjustment part has a low transmittance part in which a transmittance of light is lower than a predetermined value and a high transmittance part in which a transmittance of light is higher than that of the low transmittance part, and adjusts a transmittance of light from the plurality of light source parts. Each of the light source parts includes a first light source and a second light source having different light-emission colors to be alternately switched on lighting. The low transmittance part is arranged within an area corresponding to the plurality of light source parts. The high transmittance part is located based on a midpoint position where the distance from the adjacent light source parts is equal in the circumferential direction between the light source parts.

Provided is a display device for which the display content is easily viewed. A display device comprises: a cover plate having a gauge section on which an index is represented and a light transmitting portion that transmits light from the back; a needle that rotates on the gauge section and points to the index; and a display that is disposed behind the light transmitting portion and shows an image via the light transmitting portion. When viewing the display device in planar view, the gauge section has an overlapping region that overlaps with a portion of a display section where the display emits light, and the cover plate adheres to the display by a transparent resin that is between the cover plate and the display and spans at least the region of the light transmitting portion.
