破損してしまうという問題があった。2. Description of the Related Art At present, in the field of aircraft and the like, night-vision spectacles are used which are capable of recognizing objects on the ground, humans, etc. under the brightness of starlight. The night-vision spectacles amplify light in the near-infrared region, that is, light having a wavelength of about 600 to 900 [nm] by an electron multiplier so as to be able to recognize an object or the like illuminated by starlight. However, in the cockpit in which the night-vision spectacles having the above-mentioned configuration are used, various artificial lights emitted from LEDs, lamps, etc. of the display device and exhibiting strong emission intensity in the near infrared region exist. Such artificial light has an intensity of hundreds to tens of millions of times that of starlight in the near infrared region. When the light in the near-infrared region with such an intensity is amplified by the electron multiplier, the observer becomes too dazzling to recognize the object,
In addition, there is a problem in that the light-receiving surface of the night-vision spectacles may be burned and the night-vision spectacles may be damaged.

案されている。In order to solve such a problem, in Japanese Patent Publication No. 4-242, an optical filter composed of a composite of an organic resin film colored with a dye or a resin material and a glass filter is arranged on a light emitting portion such as an LED. However, there has been proposed a night-vision spectacle-compatible display device configured to suppress light in the near-infrared region, which is harmful to night-vision spectacles.

読み取れないという問題があった。However, as shown in FIG. 5 of the publication, the optical filter in the above-mentioned conventional display device for night-vision spectacles has a range of near-infrared region harmful to night-vision spectacles. Although the light transmittance can be suppressed only to about 1 × 10 −4 (relative value), the light (visible light) transmittance in the vicinity of about 400 to 600 [nm] is suppressed to 50 or less, and the night vision glasses It was by no means an efficient optical filter for a compatible display device. Especially, about 400-600
Since the transmittance of light in the vicinity of [nm] is suppressed to 50 or less, the brightness of the LED or the like is significantly impaired,
During the daytime when the night-vision glasses are not used, there is a problem that the displayed characters are dark and unreadable.
