Definitions

  • the present invention relates to an optical filter containing a squarylium dye metal complex compound and a display panel filter using the same. More specifically, the present invention relates to an optical filter characterized by containing a specific squarylium dye metal complex compound and a filter for a display panel using the same, and in particular, effectively shields neon emission emitted from plasma display panel force. This is a display panel filter that can be used.
  • These color image display devices basically take the form of displaying an image using a combination of light emission of three primary colors of red, green and blue.
  • xenon and neon mixed gas is excited by discharge to emit vacuum ultraviolet light, and light emission of three primary colors is obtained by using light emission of red, blue, and green phosphors by excitation of the vacuum ultraviolet light.
  • neon orange light centered around 600 nm is emitted when returning to the ground state (see, for example, Non-Patent Document 1).
  • the plasma display has a drawback that the orange color is mixed with the red color and it is impossible to obtain a strong red color! /.
  • a color image display device absorbs light emission other than the three primary colors using a so-called bandpass filter to obtain a clear color image and correct the color balance of the image.
  • band-pass filter there are various investigations on the use of a dye. In this case, there is no absorption other than the intended absorption, and the weather resistance such as heat resistance and light resistance of the dye.
  • the color reproducibility of the color image changes due to the use environment of the color image display device itself, especially the change in the emission wavelength of the light emitting device due to the temperature change. It is necessary to consider carefully.

  • Pyrazole-based squarylium dyes that contain only OH groups as groups are described (see, for example, Patent Document 5), but these are sufficient to cut neon orange light or other unwanted light. Further improvement is demanded for the high light resistance even under high-temperature and high-humidity environmental conditions, due to changes in the emission wavelength of the light-emitting device due to changes in the operating environment temperature. It was hoped that the deterioration of the color reproducibility of the color image would be improved.
