Abstract
Description
前記中心遮光部の外郭形状は円形であり、前記外周遮光部は円環状に対応し、前記中抜きスリットは円環状に対応することが好ましい。
前記中心遮光部の外郭形状は正方形であり、前記外周遮光部は正方形形態の環状に対応し、前記中抜きスリットは正方形形態の環状に対応することが好ましい。
前記中抜きスリットの幅は2.0μm以下である。
前記外周遮光部の幅は0.5μmよりも大きく、且つ1.0μm以下である。
前記中心遮光部と外周遮光部の材質はクロムである。
図面説明は次のとおりである。
具体的には、前記中心遮光部1と外周遮光部3の材質は、クロム(Cr)である。
B>2.0μmの場合、カラーフィルム層ビアホール内にフォトレジスト残りが発生し、エッチング残りになって、露光の光線の回折効果に影響してしまう。
前記中心遮光部1のサイズは、異なるカラーフィルム層の貫通孔の具体的な大きさに応じて決定することができる。
