従って、反応性メソゲンの重合度が高くなり機械的特性が増強されるので、残像特性及び信頼性を改善できる。
絶縁基板に該当する第1基板110の上に複数のゲート線121及び複数の維持電極線131、135が位置する。
以下、上部表示板200について説明する。
上部表示板200と下部表示板100の間の間隔を維持するためのカラムスペーサ363が液晶層3内に配置され得る。
しかし、これに限定されず、重合反応を抑制するためにフリーラジカル(free radical)を捕獲できる化学的グループを含む多様な物質が使用され得る。本実施形態に係る重合禁止剤グループは主鎖から遠く位置する側鎖の末端側に位置するのが好ましい。
Bに対する少なくとも一つの化合物は、以下の化合物のグループ、
また、上記化学式1において、少なくとも一つの化合物Xは、以下の化合物のグループ、
少なくとも一つの化合物Yは、以下の化合物のグループ、

しかし、UV照射以前の上述のベーク又は熱処理段階において反応性メソゲンが予め重合されるので、後続工程である光照射によって重合反応してプレチルトを形成する程度が弱く場合があった。しかし、本実施形態に係る配向膜11、21の側鎖には重合禁止剤グループを含むので、反応性メソゲンが予め重合する現象を防止できる。
一方、実施例1は、前述の化学式2で表現される化合物を含む第1共重合体のように側鎖に重合禁止剤グループを含むように配向膜を形成し、下記化学式6(これは、前述の化学式RM−5と同一)で表現される反応性メソゲンを使用した場合である。比較例1の反応性メソゲンは実施例1の反応性メソゲンに比べて熱及び光に対する反応性が劣る特性を有する。
