本申请的技术方案中，由于提供的液晶面板包括彩膜基板1、阵列基板2和第一偏光板3，彩膜基板1和阵列基板2之间填充有液晶5，第一偏光板3设置在彩膜基板1远离液晶5的一侧，同时，液晶面板还包括设置于彩膜基板1靠近液晶5的一侧的第一控光结构，且第一控光结构用于对穿过液晶5的光线进行发散，即本申请可以通过设置位于彩膜基板1的靠近液晶5的一侧的第一控光结构来对穿过液晶5的光线进行发散，从而能够提升液晶面板的观看视角，改善观看体验。
在一实施例中，第一控光结构包括若干平行且间隔设置的第一控光条6，且第一控光条6为三棱柱结构，每一第一控光条6的一侧面与彩膜基板1贴合。第一控光条6为三棱柱结构，即第一控光条6包括与彩膜基板1贴合的第一底面和与底面连接的两个第一折射面，两个第一折射面远离第一底面的一端相交，第一控光条6可以将射入两个第一折射面的光集聚，再通过第一底面发散射出，以提升视角。同时，可以通过若干个三棱柱结构的第一控光条6进一步加强对穿过液晶5的光线的发散。当然，在本申请中，第一控光条6也可以半圆柱体，且第一控光条6的圆弧面应与液晶5相对。
在一实施例中，液晶面板还包括设置于第一偏光板3远离彩膜基板1的一侧的第二控光结构（未标示），以对出射光线进行聚集。即可以通过第二控光结构将透过第一偏光板3而发散的光集聚以提升正视的亮度，避免被第一控光结构的发散作用削减液晶面板的正视亮度。需要特别说明的是，第二控光结构可以直接设置在第一偏光板3上且位于第一偏光板3远离彩膜基板1的一侧，当然第二控光结构也可以是设置在其他的安装板上。
同时，第二控光结构包括若干平行且间隔设置的第二控光条7，且第二控光条7为三棱柱结构，每一第二控光条7的一侧面与第一偏光板3贴合。第二控光条7为三棱柱体，即第二控光条7包括与第一偏光板3贴合的第二底面和与第二底面连接的两个第二折射面，两个第二折射面远离第二底面的一端相交，第二控光条7可以将射入第二底面的发散光通过两个第二折射面进行集聚，以提升亮度。同时，可以通过设置若干个三棱柱结构的第二控光条7加强对透过第一偏光板3而发散的光集聚，以提高正视亮度。当然本申请不限于此，第二控光条7也可以是半圆柱体，且第二控光条7的圆弧面背离第一偏光板3。
在一实施例中，液晶面板既包括设置于彩膜基板1靠近液晶5的一侧的第一控光结构，也包括设置于第一偏光板3远离彩膜基板1的一侧的第二控光结构，且第一控光结构包括若干平行且间隔设置的第一控光条6，第二控光结构包括若干平行且间隔设置的第二控光条7，一个第一控光条6平行于一个第二控光条7。通过分别在彩膜基板1靠近液晶5的一侧设置若干个第一控光条6，以及在第一偏光板3远离彩膜基板1的一侧设置若干个第二控光条7，且第一控光条6及第二控光条7均为三棱柱结构，且第一控光条6的一侧面贴合彩膜基板1，第二控光条7的一侧面贴合第一偏光板3，这样的设置方式使得在提升液晶面板的观看视角时，能够保证液晶面板的正视亮度，以进一步改善观看体验。
在一实施例中，每一第一控光条6在第二控光结构上的投影位于相邻两个第二控光条7之间的间隙处。即第一控光条6和第二控光条7彼此相互错开设置，以避免第一控光条6的发散作用和第二控光条7的集聚作用彼此被削弱。
另外，参见图1至图3，彩膜基板1上间隔设置有多个单色彩膜（未示出），其中，第一控光条6和第二控光条7均平行于单色彩膜。单色彩膜包括红色彩膜11、蓝色彩膜12和绿色彩膜13，且红色彩膜11、蓝色彩膜12和绿色彩膜13依次间隔排列，相邻两个单色彩膜之间设置有光阻14。由于第一控光条6和第二控光条7均平行于单色彩膜，因此能够保证第一控光条6发散的光最大限度地射入单色彩膜中。
在一实施例中，第一控光条6与彩膜基板1贴合的侧面的边长与第二控光条7的与第一偏光板3贴合的侧面的边长之和小于像素单元的宽度的2/3。像素单元的宽度等于单色彩膜的宽度。例如，第一控光条6与彩膜基板1贴合的侧面的边长的宽度为d 1，第二控光条7与第一偏光板3贴合的侧面的边长的宽度为d 2，像素单元的宽度为d 3，即d 1+d 2≤2/3d 3。在满足d 1+d 2≤2/3d 3的条件情况下，使得液晶面板能够保证有足够的光从正视方向射出，满足液晶面板的正视亮度要求。在一实施例中，d 1与d 2的宽度可以为3微米至15微米。
在一实施例中，第一控光条6可以采用感光树脂制作而成，第二控光条7可以采用紫外光固化胶制作而成。第一控光条6采用的感光树脂的折射率应该大于光阻14的折射率，光阻14的折射率一般为1.4至1.5左右，且可以在感光树脂中引入硫元素，感光树脂中硫元素通常是以硫醚键、硫酯键等形式引入，也可以通过环硫的形式将硫元素引入聚合物单体中，如此制作的感光树脂折射率在 1.5以上。当然，引入芳香族化合物或者卤族元素等也可以实现高折射率，在此不做具体的限制。感光树脂导光条可以使用曝光显影、转印、压印等方式制造。第二控光条7可以通过将紫外光固化胶在第一偏光板3外压印成形后再光照固化，也可以在 PET（聚对苯二甲酸乙二醇酯，Polyethyleneterephthalate）、PMMA（聚甲基丙烯酸甲酯，polymethyl methacrylate）、PC（聚碳酸酯，polycarbonate）等基材上先制作出棱镜结构，再贴在第一偏光板3上。
此外，本申请还包括一种显示设备，其中，显示设备包括背光单元以及根据以上所述的液晶面板。由于显示设备采用了上述实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
