本申请针对现有液晶显示装置存在边界漏光的技术问题,本申请实施例用以解决该问题。
如图1所示，现有液晶显示装置包括液晶显示面板、背光模组12和边框13，所述液晶显示面板包括对合设置的阵列基板114和彩膜基板112，在阵列基板114与彩膜基板112之间设有液晶113，所述彩膜基板112上设有偏光片111所述彩膜基板112与偏光片111在阵列基板114上的投影重合，所述阵列基板114一侧设有偏光片115，在阵列基板114上连接有覆晶薄膜116，图中箭头表示出光方向，由于需要在阵列基板上贴合覆晶薄膜，使得彩膜基板的尺寸小于阵列基板，从而造成液晶显示面板漏光，所以现有液晶显示装置存在边界漏光的技术问题。
如图2所示，本申请实施例提供一种液晶显示面板，该液晶显示面板包括：
阵列基板22；
彩膜基板24，与所述阵列基板22对合设置，所述彩膜基板24在小于阵列基板22的一端形成台阶区28；
第一偏光片21，设置于阵列基板21远离彩膜基板24的一侧；
第二偏光片25，设置于彩膜基板24远离阵列基板21的一侧；
其中，所述第一偏光片21的吸收轴与第二偏光片25的吸收轴至少在对应台阶区28的区域垂直。
本申请实施例提供一种液晶显示面板，该液晶显示面板包括阵列基板、彩膜基板、第一偏光片和第二偏光片，所述彩膜基板与所述阵列基板对合设置，所述彩膜基板在小于阵列基板的一端形成台阶区，所述第一偏光片设置于阵列基板远离彩膜基板的一侧，所述第二偏光片设置于彩膜基板远离阵列基板的一侧，其中，所述第一偏光片的吸收轴与第二偏光片的吸收轴至少在对应台阶区的区域垂直；通过使第一偏光片的吸收轴与第二偏光片的吸收轴至少在对应台阶区的区域垂直，从而使对应台阶区的区域的光无法透出，进而解决了现有液晶显示装置存在边界漏光的技术问题。
如图3、图4所示，本申请实施例提供一种液晶显示面板，该液晶显示面板包括阵列基板22、彩膜基板24，所述阵列基板22与彩膜基板24之间设有液晶23，所述阵列基板22上设有第一偏光片21，所述彩膜基板24上设有第二偏光片25，所述第一偏光片21的吸收轴与第二偏光片25的吸收轴在对应阵列基板的区域垂直。
在本申请实施例中，第一偏光片的吸收轴与第二偏光片的吸收轴垂直设置，例如图3、图4中以第一偏光片上的箭头与第二偏光片上的箭头垂直表示，如图4所示，在未设置液晶的区域，自然光201在经过第二偏光片25后得到偏振光202，偏振光202经过第一偏光片21后被吸收，虚线203表示未有光线通过，即当第一偏光片的吸收轴与第二偏光片的吸收轴垂直时，光线将不能透出，而在设有液晶的区域，即使第一偏光片的吸收轴与第二偏光片的吸收轴垂直，但由于液晶的偏转，使得光线能够透出，在下述实施例中不在叙述。
在一种实施例中，如图2所示，阵列基板22与彩膜基板24之间设有液晶23，在台阶区28对应阵列基板22的区域连接有覆晶薄膜26，通过将第二偏光片增大，且使得第二偏光片的吸收轴与与第一偏光片的吸收轴在对应阵列基板的区域垂直，由于第一偏光片的吸收轴与第二偏光片的吸收轴垂直，使得光线在经过第一偏光片和第二偏光片后无法透出，从而防止液晶显示面板漏光。
在一种实施例中，第一偏光片的吸收轴与第二偏光片的吸收轴在对应阵列基板的区域垂直，且第一偏光片与第二偏光片在阵列基板上的投影重合，即将第二偏光片增大至与第一偏光片大小一致，且使第一偏光片与第二偏光片形状相同，从而使得在防止液晶显示面板漏光的同时，使得液晶显示面板的边界齐整，无需在后续增加工序来去除多余的边界。
如图5、图6所示，本申请实施例提供一种液晶显示面板，该液晶显示面板包括阵列基板22、彩膜基板24以及设置在阵列基板22与彩膜基板24之间的液晶23，所述彩膜基板24在小于阵列基板22的一端形成台阶区28，所述阵列基板22上设有第一偏光片21，所述彩膜基板24下设有第二偏光片25，在台阶区28上对应阵列基板22的区域连接有覆晶薄膜26，在台阶区28设有填充层27，所述第一偏光片21的吸收轴与第二偏光片25的吸收轴在对应阵列基板的区域垂直；在本实施例中，使第一偏光片的吸收轴与第二偏光片的吸收轴垂直，从而防止液晶显示面板在对应台阶区的区域漏光，且在阵列基板与第二偏光片之间设置填充层，所述填充层可防止第二偏光片在受到压力时弯折甚至折断，从而防止第二偏光片在出现弯折或者折断时会导致对应台阶区的区域漏光，进而解决了现有液晶显示装置存在边界漏光的技术问题。
在一种实施例中，如图6所示，所示第一偏光片21包括第一子偏光片211与第二子偏光片212，所述第一子偏光片211设置于对应台阶区28的区域，所述第二子偏光片212设置于不对应台阶区28的区域，所述第一子偏光片211的吸收轴与第二偏光片25的吸收轴垂直，所述第二子偏光片212的吸收轴与第二偏光片25的吸收轴平行，通过将第一偏光片划分为第一子偏光片和第二子偏光片，使得只需使对应台阶区的区域的第一子偏光片的吸收轴与第二偏光片的吸收轴垂直，即可使得对应台阶区的区域的光无法透过，进而防止液晶显示面板漏光。
在一种实施例中，第一子偏光片的吸收轴与第二子偏光片的吸收轴均与第二偏光片的吸收轴垂直，本申请实施例不限定第二子偏光片的吸收轴与第二偏光片的吸收轴的状态，以实际过程中第二子偏光片的吸收轴与第二偏光片的吸收轴的状态决定。
在一种实施例中，填充层在对应台阶区的区域整面设置，且所述第二偏光片与所述填充层接触的平面和所述第二偏光片与所述彩膜基板接触的平面相同，从而使得第二偏光片平整，进而防止第二偏光片出现弯折，防止液晶显示面板漏光。
在一种实施例中，所述填充层为透明材料，或者所述填充层为遮光材料，在使第一偏光片的吸收轴与第二偏光片的吸收轴垂直的同时，使得设置的填充层为遮光材料，进一步的防止液晶显示面板漏光。
在一种实施例中，所述填充层为树脂，例如聚酰亚胺树脂、聚乙烯树脂、聚丙烯树脂、酚醛树脂等。
如图7所示，本申请实施例提供一种液晶显示面板，该液晶显示面板包括阵列基板32、彩膜基板34以及位于阵列基板32与彩膜基板34之间的液晶33，所彩膜基板34在小于阵列基板32的一端形成台阶区38，所述阵列基板32的下方设有第一偏光片31，所述台阶区38上对应阵列基板的区域32连接有覆晶薄膜36，所述彩膜基板34的上方设有第二偏光片35，所述第二偏光片35与阵列基板32之间设有填充层37，所述第二偏光片35包括第三子偏光片352和第四子偏光片353，所述第三子偏光片352设置于对应所述台阶区38的区域，所述第四子偏光片设置于不对应所述台阶区38的区域，所述第三子偏光片352的吸收轴与第一偏光片31的吸收轴垂直，所述第四子偏光片351的吸收轴与第一偏光片31的吸收轴平行。
在本实施例中，将第二偏光片划分为第三子偏光片与第四子偏光片，所述第三子偏光片的吸收轴与第一偏光片的吸收轴垂直，从而使得对应台阶区区域的光线无法透出，进而防止液晶显示面板漏光，且在第三子偏光片与第一偏光片之间设置透明层，可防止第三子偏光片弯折甚至折断，且防止第三子偏光片掉落，进而解决了现有液晶显示装置存在边界漏光的技术问题。
在一种实施例中，第三子偏光片与第四子偏光片位于不同平面上，在本申请实施例中，并不限制第三子偏光片与第四子偏光片处于同一平面上，在保证第三子偏光片的吸收轴与第一偏光片的吸收轴垂直的前提下，第三子偏光片可略低于第四子偏光片，对于不平整的部分，可使用填充层来填充，进而使得显示面板平整。
在一种实施例中，填充层可有多个圆柱体构成，考虑到填充层主要作为支撑作用，可使用间隔设置的圆柱体来支撑第三子偏光片，且本申请实施例不限定填充层的形状，以能够支撑第三子偏光片为目的设置。
如图8所示，本申请实施例提供一种液晶显示装置，该液晶显示装置包括液晶显示面板、背光模组42和边框43，所述液晶显示面板包括阵列基板412、彩膜基板414以及位于阵列基板412和彩膜基板414之间的液晶413，所述彩膜基板414在小于阵列基板412的一端形成台阶区418，所述阵列基板412上设置有第一偏光片411，所述台阶区418上对应阵列基板412的区域连接有覆晶薄膜416，所述彩膜基板414上设有第二偏光片415，所述第二偏光片415与所述阵列基板412之间设有填充层417，所述第一偏光片411的吸收轴与第二偏光片415的吸收轴在对应阵列基板412的区域垂直，在对应台阶区的区域，背光模组42发出的光经过第一偏光片411和第二偏光片415，将无法透出，即防止了液晶显示装置在对应台阶区的区域漏光，进而解决了现有液晶显示装置存在边界漏光的技术问题。
本申请实施例提供一种液晶显示装置，该液晶显示装置包括背光模组、液晶显示面板和边框，该液晶显示面板包括阵列基板、彩膜基板、第一偏光片和第二偏光片，所述彩膜基板与所述阵列基板对合设置，所述彩膜基板在小于阵列基板的一端形成台阶区，所述第一偏光片设置于阵列基板远离彩膜基板的一侧，所述第二偏光片设置于彩膜基板远离阵列基板的一侧，其中，所述第一偏光片的吸收轴与第二偏光片的吸收轴至少在对应台阶区的区域垂直；通过使第一偏光片的吸收轴与第二偏光片的吸收轴至少在对应台阶区的区域垂直，从而使对应台阶区的区域的光无法透出，进而解决了现有液晶显示装置存在边界漏光的技术问题。
