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.

スクァリリウム色素一金属錯体化合物を含有する光学フィルター及びこれ を用いたディスプレイパネル用フィルター 技術分野  Optical filter containing squarylium dye monometallic complex compound and display panel filter using the same
[0001] 本発明は、スクァリリウム色素 金属錯体化合物を含有する光学フィルター及びこ れを用いたディスプレイパネル用フィルターに関する。詳しくは、特定のスクァリリウム 色素 金属錯体化合物を含有することを特徴とする光学フィルター及びこれを用い たディスプレイパネル用フィルターに関するもので、特にプラズマディスプレイパネル 力、ら放射されるネオン発光を有効に遮蔽することができるディスプレイパネル用フィル ターである。  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.
背景技術  Background art
[0002] 従来より、カラー画像の表示装置として、陰極管、蛍光表示管、電界放射、プラズマ パネル、液晶、エレクト口ルミネッセンス等による各種画像表示装置が開発されている 。特に、近年、大型の壁掛けテレビをはじめ種々の電子機器の表示パネルとしてブラ ズマディスプレイパネルが使用され、その需要が増大し、今後もその数は益々増加す るあのと考免られる。  Conventionally, various types of image display devices using a cathode tube, a fluorescent display tube, a field emission, a plasma panel, a liquid crystal, an electoluminescence, etc. have been developed as color image display devices. In particular, in recent years, plasma display panels have been used as display panels for various types of electronic devices such as large-sized wall-mounted televisions, and the demand for them has increased, and the number of such displays will continue to increase.
[0003] これらカラー画像の表示装置は、基本的には赤、緑、青の 3原色発光の組み合わ せを利用し画像表示をする形式をとつている。特にプラズマディスプレイでは、放電 によりキセノンとネオンの混合ガスが励起され真空紫外線を放射し、その真空紫外線 励起による赤、青、緑のそれぞれの蛍光体の発光を利用して 3原色発光を得ている。 プラズマディスプレイでは、その際、ネオン原子が励起された後、基底状態に戻る際 に 600nm付近を中心とするいわゆるネオンオレンジ光を発光する(例えば、非特許 文献 1参照)。このため、プラズマディスプレイでは、赤色にオレンジ色が混ざり鮮ゃ 力、な赤色が得られな!/、欠点がある。  [0003] 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. In particular, in plasma displays, 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. . In the plasma display, after neon atoms are excited, so-called neon orange light centered around 600 nm is emitted when returning to the ground state (see, for example, Non-Patent Document 1). For this reason, 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! /.
[0004] カラー画像の表示装置では一般的に、上記 3原色以外の発光を、いわゆるバンド パスフィルターを用いて吸収し、鮮明なカラー画像を得、かつ、画像の色バランスの 補正が行われている。 [0005] 該バンドパスフィルタ一としては色素を用いたものの検討が各種なされている力 こ の場合、 目的とする吸収以外に吸収がないこと、及び、色素の耐熱性'耐光性等の 耐候性が重要な因子となるが、さらに、カラー画像の表示装置自体の使用環境、特 に温度変化による発光装置の発光波長変化によりカラー画像の色再現性が変わると いう問題があり、この点にも十分に考慮する必要がある。 In general, 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. Yes. [0005] As the 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. However, there is also a problem that 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.

そして上述した特許文献 1〜3のスクァリリウム金属化合物については、いずれも光 学フィルターとしての記述は見られな!/、。  Regarding the squarylium metal compounds of Patent Documents 1 to 3 described above, no description as an optical filter can be seen! /.
[0016] また、スクァリリウム色素を光学フィルタ一として利用した例としては、特定のスクァリ リウム色素を用いたカラーフィルターの例(例えば、特許文献 4参照)や、さらにスクァ リリウム色素のベンゼン環上の置換基として OH基のみを有する化合物ゃピラゾール 系スクァリリウム色素が記載されているが(例えば、特許文献 5参照)、これらはネオン オレンジ光をカット、あるいはその他の不要な光をカットするには十分である力 S、化合 物の耐候性、特に、高温高湿の環境条件においても高い耐光性を有することについ てはさらなる改良が望まれており、さらに、使用環境温度変化による発光装置の発光 波長変化によって引き起こされるカラー画像の色再現性の劣化についても改良が望 まれて V、た。 [0016] Examples of using the squarylium dye as an optical filter include a color filter using a specific squarylium dye (see, for example, Patent Document 4), and further substitution of the squarylium dye on the benzene ring. 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.
[0017] 以上の現状に鑑み、さらなる化合物の耐候性向上とともに、使用環境温度変化によ る発光装置の発光波長が変化しても、鮮明なカラー画像を得ることのできる光学フィ ルターならびにこれを用いたディスプレイパネル用フィルターが望まれている。  [0017] In view of the above situation, an optical filter capable of obtaining a clear color image even when the light emission wavelength of the light-emitting device changes due to a change in the use environment temperature as well as further improving the weather resistance of the compound, and the The display panel filter used is desired.
