Abstract
Description
また、本開示は、説明の便宜のために例示的に直下型(direct light type)の液晶表示パネルとして説明する。しかし、本開示の思想は、他の形態、例えば、側光型(side light type)の液晶表示パネルにも同様に適用できる。
支持層(221)は、下部から上部に進行する光が通過できるように透明な材質から形成されてもよい。支持層(221)は、光拡散層(220)の剛性を確保する役割をする。支持層(221)は、例えば、PET(polyethylene terephthalate)から形成されてもよい。
すなわち、本実施例による複合シート層(200)は、第1層(L1)、複数のビーズ(221)及び第2層(L2)を含む接着層(210)を含み得る。接着層(210)の下部には、互いに対向する3つの支持層(221)を含み、互いに対向する支持層(221)の間には、複数の第1プリズム(222)及び複数の第2プリズム(223)が配置されてもよい。図8において、図4を参照して上述したように、第1の層L1の厚さは、第2の層L2の厚さと同じであっても異なっていてもよい。例えば、第1層L1の厚さと第2層L2の厚さが同一である場合、複数のビード211が接着層210の中央に形成され得る。仮想線VL上で、第1層L1の厚さは、第2層L2の厚さより大きくてもよい。すなわち、複数のビーズ211は、接着層210内の上面により近く形成され得る。これは、光を水平方向に拡散させるのにより有利である。
