Description
S501:ベース基板に第1の導電薄膜を形成し、パターニング工程により複数のゲートライン及びVcom線を形成し、各行における各画素ユニットに対応するVcom線は電気的に接続される。
一実施例において、マグネットスパッタリング法により、例えばベース基板とするガラス基板のベース基板に1層の1000Å〜7000Åの厚さを有する金属薄膜を形成する。金属薄膜の材料として、通常モリブデンや、アルミニウムや、タングステンモリブデン合金や、クロムや、銅などを採用し、これら材料の薄膜により構成された複合層を採用してもよい。そして、マスクによる露光・現像や、エッチングや、剥離などを含むパターニング工程を利用して、図5に示したように、ガラス基板の一定の領域に、ゲート電極に接続される複数の横方向のゲートラン1とVcom線4を形成し、当該Vcom線4の各行における各画素ユニット(即ち、各画素における)に対応するVcom線4が電気的に接続される。
一実施例において、ゲートラインの形成と類似した方法を採用し、ガラス基板に1層の1000Å〜7000Å厚さの金属薄膜を堆積する。その材料として、ゲートラインの金属材料と類似している。図6に示したように、マスクによるパターニング工程によって、前記金属薄膜に対してパターニングし、一定の領域でデータライン2と、薄膜トランジスタ(TFT)のソース電極及びドレイン電極とを形成し、ソース電極とドレイン電極の間に活性層を介してチャンネルを形成することで、ソース電極、ドレイン電極、活性層及び前で形成されたゲート電極により薄膜トランジスタが形成する。
一実施例において、ゲート絶縁層や、活性層の形成と類似した方法を採用し、ガラス基板の全体に1層の1000Å〜6000Å厚さのパッシベーションを形成(例えば、塗布)する。パッシベーションの材料として、窒化ケイ素又は透明な有機樹脂材料が採用される。この場合、ゲートラインとデータラインに同一厚さのパッシベーション層が覆われる。図7に示したように、パターニング工程によって前記パッシベーションに対してパターニングを行い、ドレイン電極とVcom線が対応する位置に接続部ホール81,82を形成する。
一実施例において、ガラス基板の全体におけるパッシベーションに、1層の画素電極薄膜層を堆積する。一般的に、画素電極薄膜層として、インジウムスズ酸化物(Indium Tin Oxide、ITO)、又はインジウム亜鉛酸化物(IZO:Indium Zinc Oxide)が採用され、厚さは100Åから1000Åの範囲である。
