Abstract
Description
図1は、本発明の実施の形態1におけるPDP10の分解斜視図である。PDP10は、前面板20と背面板30とを対向配置し、周辺部を低融点ガラス(図示せず)を用いて封着することにより構成されており、内部に多数の放電セルが形成されている。
黒色感光性ペーストは、ガラス基板21上に塗布し乾燥して第1の感光性膜(以下、「黒色感光性膜」とする)を形成し、その後露光することにより、黒色層221b、222b、231b、232bおよびアライメントマークを形成するための感光性ペーストである。黒色感光性ペーストは、固形分としての黒色材料とガラス粉末とを含む無機材料成分と、感光性ポリマーと感光性モノマーと光重合開始剤とを含む有機材料成分とからなり、上記黒色材料の粒径は1μm以下である。
導電性感光性ペーストは、黒色感光性膜上に塗布、乾燥して第2の感光性膜(以下、「導電性感光性膜」とする)を形成し、その後、露光することにより、導電層221c、222c、231c、232cを形成するための材料である。導電性感光性ペーストは、銀を主成分とする導電性材料とガラス粉末とで構成される無機材料成分と、光硬化性ポリマーなどの感光性ポリマー、感光性モノマー、光重合開始剤、溶媒などの各種有機材料成分を所定の組成となるように調合した後、均質に混合分散し作成する。
誘電体ペーストは、誘電体層26を形成するための材料である。誘電体ペーストは、酸化硼素、酸化珪素、酸化亜鉛、アルカリ土類酸化物、アルカリ金属酸化物、酸化ビスマス、酸化アルミニウム、酸化モリブデン、酸化タングステン、酸化セリウムなどの中からいくつかを含んだ軟化点520℃~590℃の誘電体ガラスを含むペーストである。
第1ステップでは、基板として、ガラス基板21を前面側に用い、ガラス基板21上に黒色感光性ペーストを塗布し乾燥して第1の感光性膜としての黒色感光性膜bxを形成する。まずガラス基板21をアルカリ洗浄する。ガラス基板21は、42インチのPDPであれば、例えば、大きさが980mm×554mm、厚みが1.8mmのガラス基板である。
第2ステップでは、第1の露光マスクを用いて黒色感光性膜bxを露光してアライメントマークを形成する。第1の露光マスク41には、バス電極221、222、231、232を形成するためのパターンとアライメントマーク51を形成するためのパターンとが形成されている。
第3ステップでは、図3Dに示すように、黒色感光性膜bxを現像する前の状態でアライメントマーク51を認識して、走査電極22および維持電極23を形成するための第2の露光マスク42の位置合わせを行い、黒色感光性膜bxの2回目の露光を行う。このとき黒色感光性膜bxの表面に形成されたアライメントマーク51に光を照射し、アライメントマーク51をカメラで撮像して第2の露光マスクの位置決めを行う。第2の露光マスク42には、バス電極221、222、231、232を形成するためのパターンが形成されている。しかし第2の露光マスク42に形成されているパターンは第1の露光マスク41のパターンの幅よりもやや狭く設計されている。本実施の形態においては、第1の露光マスク41に形成されているバス電極221、222、231、232のパターンの幅よりも20%程度狭いパターンが第2の露光マスク42に形成されている。このときアライメントマーク51を照射する光が拡散しすぎるとアライメントマーク51を精度よく撮像できない。よって、同軸落射照明系を用いて直線状の光をアライメントマーク51に照射し、反射光の濃淡を撮像することによって、アライメントマーク51を認識することが望ましい。なお、段差の振れ幅が0.5μm未満の場合には、同軸落射照明系を用いてもアライメントマークを十分に認識できない場合がある。また、2回目の露光強度は、例えば200mJ/cm2である。
第4ステップでは、黒色感光性膜bxを現像して走査電極22および維持電極23を形成する。具体的には、図3Eに示すように、黒色感光性膜bxの現像を行って黒色層221b、222b、231b、232bの前駆体221bx、222bx、231bx、232bxおよび導電層221c、222c、231c、232cの前駆体221cx、222cx、231cx、232cxを形成する。なお、現像後、必ずしもアライメントマーク51がガラス基板21上に残存するわけではない。しかし第2の露光マスク42を用いて2回目の露光を行う際に、第2の露光マスク42の位置決め用の孔を通してアライメントマーク51も露光されるため、通常はアライメントマーク51がガラス基板21上に残存する。
第5ステップでは、図3Gに示すように、バス電極221、222、231、232が形成されたガラス基板21上に、スクリーン印刷法、ダイコート法などにより、誘電体ペーストを塗布し、乾燥して誘電体層26の前駆体(図示せず)を形成する。そして誘電体層26の前駆体(図示せず)を焼成して、厚み20μm~50μmの誘電体層26を形成する。本実施の形態においては、誘電体層26の前駆体(図示せず)を約590℃で焼成して、厚みが約40μmの誘電体層26を形成した。
実施の形態2におけるPDPの構造は、図1、図2Aおよび図2Bに示した構造と同じである。また、使用する各種ペーストも実施の形態1と同様である。実施の形態2が実施の形態1と異なるところは、黒色感光性ペーストをガラス基板21に塗布し乾燥した後に、アライメントマークを形成するための露光を行い、その後、導電性感光性ペーストを塗布する点である。
第1ステップでは、前面側のガラス基板21上に黒色感光性ペーストを塗布し乾燥して第1の感光性膜としての黒色感光性膜bxを形成する。
第2ステップでは、図7Bに示すように、黒色感光性膜bxを露光して少なくとも第1のアライメントマークと第2のアライメントマークとを形成する。
第3ステップでは、図7Dに示すように、第1のアライメントマーク56を認識して第2の露光マスク46を位置合わせし、走査電極22および維持電極23を形成するための1回目の露光を行う。具体的には、黒色感光性膜bxの表面に形成された第1のアライメントマーク56に光を照射し、第1のアライメントマーク56をカメラで撮像して、第2の露光マスク46の位置決めを行う。このときも同軸落射照明を用いることが望ましい。第2の露光マスク46には、バス電極221、222、231、232を形成するためのパターンが形成されている。このときの露光強度は、例えば200mJ/cm2である。
第4ステップでは、図7Fに示すように、現像処理を行うことにより、黒色層221b、222b、231b、232bの前駆体221bx、222bx、231bx、232bxおよび導電層221c、222c、231c、232cの前駆体221cx、222cx、231cx、232cxを形成する。
第5ステップでは、図7Hに示すように、バス電極221、222、231、232が形成されたガラス基板21上に、スクリーン印刷法、ダイコート法などの公知技術により、誘電体ペーストを塗布し、乾燥して誘電体層26の前駆体(図示せず)を形成する。そして誘電体層26の前駆体(図示せず)を焼成して、厚み20μm~50μmの誘電体層26を形成する。
