请参考图1，本揭示提供一种液晶显示器100的制造方法，其包括下列步骤。
步骤1：提供液晶显示面板10。所述液晶显示面板10包含在其相对两侧的入光面111及出光面121。具体地，所述液晶显示面板10包含阵列基板11、彩膜基板12及液晶层15。所述阵列基板11与所述彩膜基板12相对设置。所述液晶层15设置在所述阵列基板11与所述彩膜基板12之间。所述液晶显示面板10的入光面111为所述阵列基板11远离液晶层15的表面。所述液晶显示面板10的出光面121为所述彩膜基板12远离液晶层15的表面。
步骤2：设置第一偏光片20于所述液晶显示面板10的入光面111，及/或设置第二偏光片30于所述液晶显示面板10的出光面121。在一实施例中，所述液晶显示面板10可以仅设有第一偏光片20或第二偏光片30。
具体地，所述设置第一偏光片20于入光面111包含：涂布胶粘剂于第一偏光片20或入光面111，以形成胶粘剂层8，以及通过胶粘剂层8将第一偏光片20贴附至入光面111。所述设置第二偏光片30于出光面121包含：涂布胶粘剂于第二偏光片30或出光面121，以形成胶粘剂层8，以及通过胶粘剂层8将第二偏光片30贴附至出光面121。所述胶粘剂可为压敏胶(Pressure Sensitive Adhensive，PSA)。所述压敏胶可为聚丙烯类胶，但不限于此。
在一实施例中，第一偏光片20及第二偏光片30的位置可以互换。即，步骤2亦可为：设置第一偏光片20于所述液晶显示面板10的出光面121，及/或设置第二偏光片30于所述液晶显示面板10的上入光面111。
步骤3：当所述入光面111设有所述第一偏光片20时，直接形成第一减反射膜40于所述第一偏光片20远离所述液晶显示面板10的表面。当所述出光面121设有所述第二偏光片30时，直接形成第二减反射膜50于所述第二偏光片30远离所述液晶显示面板10的表面。具体地，可通过真空蒸镀或溅射将减反射材料沉积于所述第一偏光片20及所述第二偏光片30，来分别形成第一减反射膜40及第二减反射膜50，但不限于此。所述减反射材料可为具有低折射率及高强度的材料，诸如氟化镁。所述第一减反射膜40及第二减反射膜50的材料可相同或不同。
为了达成减反射的目的，第一减反射膜40的第一厚度可基于第一减反射膜40的第一折射率及背光板发出的第一光线101的光谱进行调整，以使第一减反射膜40的上下界面所反射的光干涉相消。
为达到较佳的减反射的效果，可通过下列公式(I)计算出第一减反射膜40的较佳第一厚度e 1。
Figure PCTCN2020122934-appb-000001
e 1为第一减反射膜40的第一厚度，λ 1为第一光线101的第一波长，以及n 1为第一减反射膜40的第一折射率。
由于一般玻璃基板及偏光片的折射率约为1.52，且空气的折射率为1，因此第一减反射膜40的第一折射率较佳为1.23～1.38，但不限于此。第一反射率可通过改变第一减反射膜40的材料来进行调整。第一波长可选用背光板主要提供液晶显示器10亮度的第一光线101的波长，亦即针对背光板主要提供液晶显示器10亮度的波长进行减反射。常用的背光板主要提供液晶显示器10亮度的波长为450nm及500nm-630nm，因此第一光线101的第一波长可选用450nm或500nm-630nm，但不限于此。第一波长可通过改变背光板的光谱来进行调整。当第一折射率为1.23～1.38，且第一光线101的波长为450nm或500nm-630nm时，第一减反射膜40的第一厚度较佳为81.5nm～128nm，但不限于此。
举例而言，在第一波长λ 1为450nm的情况下，若将若将第一折射率n 1设定为1.23，则第一厚度e 1较佳为91.44nm；若将第一折射率n 1设定为1.38，则第一厚度e 1较佳为81.5nm。在第一波长λ 1为500nm时，若将第一折射率n 1设定为1.23，则第一厚度e 1为101.6nm；若将第一折射率n 1设定为1.38，则所需的第一厚度e 1为90.6nm。在第一波长λ 1为550nm的情况下，若将第一折射率n 1设定为1.23，则第一厚度e 1较佳为111.8nm；若将第一折射率n 1设定为1.38，则第一厚度e 1较佳为99.7nm。在第一波长λ 1为630nm的情况下，若将第一折射率n 1设定为1.23，则第一厚度e 1较佳为128nm；若将第一折射率n 1设定为1.38，则第一厚度e 1较佳为114.2nm。
同理，为了达成减反射的目的，第二减反射膜50的第二厚度可基于第二减反射膜50的第二折射率及穿透液晶显示器10的第二光线102的穿透光谱进行调整，以使第二减反射膜50的上下界面反射的光干涉相消。
为达到较佳的减反射的效果，可通过下列公式(II)计算出第二减反射膜50的较佳第二厚度e 2。
Figure PCTCN2020122934-appb-000002
e 2为第二减反射膜50的第二厚度，λ 2为第二光线102的第二波长，以及n 2为第二减反射膜50的第二折射率。
如前所述，一般玻璃基板及偏光片的折射率约为1.52，且空气的折射率为1，因此第二减反射膜50的第二折射率较佳为1.23～1.38，但不限于此。第 二反射率可通过改变第二减反射膜50的材料来进行调整。第二波长可选用主要通过液晶显示器10的第二光线102的波长，亦即针对液晶显示器10主要产生亮度的波长进行减反射。根据常用的液晶显示器的穿透光谱，减少波长为540nm-560nm的绿色光的反射可以明显改善穿透率。因此，第二光线102的第二波长可选用540nm-560nm，但不限于此。第二波长可通过改变液晶显示器10的穿透光谱来进行调整。当第二折射率为1.23～1.38，且第二光线102的第二波长为540nm-560nm时，第二减反射膜50的第二厚度较佳为97.8nm～113.8nm，但不限于此。
举例而言，在第二波长λ 2为540nm的情况下，若将第二折射率n 2设定为1.23，则第二厚度e 2较佳为109.8nm；若将第二折射率n 2设定为1.38，则第二厚度e 2较佳为97.8nm。在第二波长λ 2为560nm的情况下，若将第二折射率n 2设定为1.23，则第二厚度e 2较佳为113.8nm；若将第二折射率n 2设定为1.38，则第二厚度e 2较佳为101.4nm。
在第一实施例中，请参考图2，所述第一偏光片20依序包含光学补偿膜21、偏振层22及保护层23。所述第二偏光片30依序包含光学补偿膜31、偏振层32、保护层33及硬化层34。所述偏振层22、32具有偏振作用。所述偏振层22、32可由聚乙烯醇(Poly Vinyl Alcohol，PVA)制成，但不限于此。光学补偿层21、31用于补偿液晶显示器10的漏光及色偏。所述保护层23、33分别用于保护偏振层22、32。所述保护层23、33可分别隔绝水汽进入所 述第一偏光片20及所述第二偏光片30。所述保护层23、33可由三醋酸纤维素(Tri-acetyl Cellulose，TAC)制成，但不限于此。所述硬化层34用以防止所述第二偏光片30被刮伤。在此实施例中，所述保护层23设置在所述第一偏光片20最远离所述液晶显示面板10的一侧，且所述第一减反射膜40直接形成于所述保护层23远离所述液晶显示面板10的表面上。再者，所述硬化层34设置在所述第二偏光片30最远离所述液晶显示面板10的一侧，且所述第二减反射膜50直接形成于所述硬化层34远离所述液晶显示面板10的表面上。在一实施例中，所述液晶显示面板10可以仅设有所述第一偏光片20及所述第一减反射膜40。在一实施例中，所述液晶显示面板10可以仅设有所述第二偏光片30及所述第二减反射膜50。
