Description
本出願は、2015年01月30日に出願された大韓民国特許出願第10−2015−0015477号並びに2016年02月01日に出願された大韓民国特許出願第10−2016−0012172号及び大韓民国特許出願第10−2016−0012170号に基づく優先権の利益を主張し、該当韓国特許出願の文献に開示されたすべての内容は本明細書の一部として組み入れるものとする。
本発明は、偏光子または偏光板に関する。
偏光度(P)(%)={(Tp−Tc)/(Tp+Tc)}1/2×100
以下の実施例で、透過率、偏光度、CIE色座標などは、JASCO V−7100Spectrophotometerを使用して製造社のマニュアルによって偏光子自体に対して測定した。
偏光子サンプルは円盤フィルムであって、平均重合度が約2400程度であり、厚さが約60μm程度であるPVAフィルムに、下記のような膨潤、染色、架橋、延伸及び洗浄工程を実行して製造した。前記工程での工程変数、例えば、処理液内でのヨウ素またはヨウ素イオンの濃度や処理液内への処理時間は、各サンプル別に下記表1に示したような特性が具現されるように調節した。膨潤は、処理液としては純水を使用し、前記PVAフィルムを膨潤浴内で適正時間浸漬して実行した。また、染色工程は、ヨウ素及びヨウ化カリウムの濃度が調節された染色液内に適正温度で適正時間PVAフィルムを浸漬させて実行し、この過程でPVAフィルムを適正範囲で延伸させた。架橋工程は、架橋浴の処理液として、ホウ酸とヨウ化カリウムを適正割合で含む水溶液にPVAフィルムを浸漬し、一定範囲で延伸して実行し、延伸工程も延伸浴の処理液として、ホウ酸とヨウ化カリウムを所定濃度で含む処理液内で実行した。次に、洗浄浴の処理液としては、ヨウ化カリウムを所定割合で含む水溶液を使用した洗浄工程と、乾燥工程を経てサンプルを製造した。前記各サンプルの特性は下記の通りである。
液晶パネルとして一般液晶パネル(550nm波長の光に対する反射率が約10.6%)と高反射液晶パネル(550nm波長の光に対する反射率が約18.18%)を使用して偏光子適用による光学特性を比較した。図10は、前記一般パネルと高反射液晶パネル(HRL)の反射特性を示す図である。図面のように、高反射液晶パネル(HRLパネル)は一般液晶パネルに比べて高い反射率を示す。
