 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
本申请实施例针对现有液晶显示器件存在黑色矩阵的宽度较大，导致液晶显示器件的开口率较低的技术问题，本申请实施例用以解决该技术问题。
如图1所示，现有液晶显示器件中为了避免相邻像素之间出现杂散光导致显示画面失真，因此会在相邻像素之间设置黑色矩阵，色阻层包括红色色阻111、蓝色色阻112、绿色色阻113，相邻色阻之间的横向间距为a1，相邻色阻之间的纵向间距为b1，但为了避免杂散光的散射，黑色矩阵层12形成的过孔121会小于色阻的大小，即相邻过孔121之间的横向间距a2大于a1，相邻过孔121之间的纵向间距b2大于a2，从而使得黑色矩阵会遮挡色阻，导致实际的发光区域小于色阻的发光区域，从而导致显示面板的开口率降低，所以，现有液晶显示器件存在黑色矩阵的宽度较大，导致液晶显示器件的开口率较低的技术问题。
如图2、图3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：
第一基板23；
第二基板21，与所述第一基板23相对设置；
其中，在所述第一基板23远离所述液晶层22的方向上设有遮光层24，所述遮光层24图案化形成有遮光图案241，所述遮光图案241设置于相邻像素之间，且遮光图案241的宽度c2（d2）与相邻像素之间的间距c1（d1）的差值小于或者等于阈值k，所述遮光图案241的材料包括无机材料。
本申请实施例提供一种液晶显示面板，通过在第一基板远离液晶层的方向设置遮光层，遮光层图案化形成有遮光图案，并使得遮光图案设置于相邻像素之间，且遮光图案的宽度与相邻像素之间的间距的差值小于或者等于阈值，遮光图案的材料包括无机材料，从而使得通过遮光图案对相邻像素之间的区域进行遮光，无需设置黑色矩阵，提高对液晶的控制能力，且由于遮光图案设置在基板外，从而对人眼侧进行遮光，无需使得遮光图案的宽度大于相邻像素之间的间距，从而提高了液晶显示面板的开口率。
需要说明的是，在液晶显示面板的设计中，会存在在横向方向上，相邻像素之间的间距，与在纵向方向上，相邻像素之间的间距不同的情况，即在图3中，c1与d1不相等，则遮光图案的宽度与相邻像素之间的比较根据相邻像素的方向确定，例如，相邻像素为纵向的两个像素，则遮光图案的宽度为d2，相邻像素为横向的两个像素，则遮光图案的宽度为c2，即使得遮光图案的宽度与相邻像素之间的间距对应；同时，还会存在相邻像素之间的间距为非等间距的情况，则相应的遮光图案的宽度进行相应的设计，以使得遮光图案对像素之间的区域进行遮光，同时，通过控制遮光图案的宽度，避免遮光图案对像素进行遮光，提高显示面板的开口率；而对于横向的相邻像素之间的间距和纵向的相邻像素之间的间距相同的情况，即图3中c1与d1相等，则遮光图案的宽度为c2或者d2中的任一值。
需要说明的是，图3中以相邻的色阻之间的间距表示相邻像素之间的间距，且在图3中，相同颜色的色阻横向排列，但本申请实施例不限于此，相同颜色的色阻可以纵向排列，或者色阻以其他像素排列方式进行排列。
需要说明的是，阈值可以为正值、0和负值，即此处限定遮光图案的宽度与相邻像素之间的间距的差值在某范围内。
在本申请实施例中，相较于现有技术中在基板内设置黑色矩阵，由于黑色矩阵为有机材料，有机材料的形成过程中，会收缩导致黑色矩阵呈现中间凹陷两边凸起的状态，从而导致液晶存在一定的预倾角（此处的预倾角指设计外由于设计缺陷导致的液晶偏转角度），从而导致影响显示，例如出现漏光，且液晶无法得到有效的控制，但本申请实施例中无需设置黑色矩阵，使得液晶能够按照设计进行排列，从而提高了液晶的控制能力。
在一种实施例中，在第一基板上设有第一配向层、在第二基板上设有第二配向层，即在液晶对盒时，会使得在第一基板和第二基板上形成配向层，从而使得液晶通过配向层进行配向，形成一定的预倾角，进而通过液晶偏转进行控制光线。
在一种实施例中，如图4所示，所述第一基板包括阵列基板21，所述阵列基板21包括第一衬底211和设置于所述第一衬底211上的驱动电路层212，以及像素电极层213，所述遮光图案241设置于所述第一衬底211远离所述驱动电路层212的方向上，对于出光方向为阵列基板侧的液晶显示面板，通过在阵列基板侧设置遮光图案，从而使得在显示面板从阵列基板侧发射出去时，遮光图案对像素之间的区域进行遮光，避免杂散光影响显示，且由于遮光图案设置于人眼侧，光线从阵列基板侧发射出来后，不会再经过其他膜层导致光线出现折射或者偏移，因此，仅需要使得遮光图案的宽度与相邻像素之间的间距的差值小于阈值即可对杂散光进行遮挡，提高了液晶显示面板的开口率。
在一种实施例中，如图2所示，所述第一基板包括彩膜基板23，所述彩膜基板23包括第二衬底234和设置于所述第二衬底234上的色阻层232，以及公共电极层231，相邻色阻间隔设置，所述遮光图案241设置于所述第二衬底234远离所述色阻层232的方向上，在设置遮光层时，针对出光方向为彩膜基板侧的液晶显示面板，通过在彩膜基板侧设置遮光图案，使得遮光图案对像素之间的区域进行遮光，避免杂散光影响显示，且由于遮光图案设置于人眼侧，光线从彩膜基板侧发射出来后，不会再经过其他膜层导致光线出现折射或者偏移，因此，无需设置黑色矩阵，且遮光图案的宽度仅需要与色阻之间的间隔的差值小于阈值即可对杂散光进行遮光，从而提高了液晶显示面板的开口率。
在一种实施例中，所述液晶显示面板包括端子区，所述遮光图案沿着垂直于端子区和端子区相对的区域的方向设置，即在设置遮光图案时，可以使得遮光图案横向设置，从而在纵向的相邻像素之间，通过设置遮光图案，无需设置黑色矩阵，从而提高了显示面板的开口率。
在一种实施例中，所述液晶显示面板包括端子区，所述遮光图案沿着端子区和端子区相对的区域的方向设置，即在设置遮光图案时，可以使得遮光图案纵向设置，从而在横向的相邻像素之间，通过设置遮光图案，无需设置黑色矩阵，从而提高了显示面板的开口率。
在一种实施例中，如图3所示，所述遮光图案241包括横向设置的第一图案和纵向设置的第二图案，所述第一图案的宽度d2与横向设置的相邻色阻的间距d1相等，所述第二图案的宽度c2与纵向设置的相邻色阻的间距c1相等，即在设置遮光图案的宽度时，遮光图案的宽度等于相邻像素之间的间距，从而使得在显示面板显示时，对应色阻的区域能够完全显示，通过遮光图案进行遮挡，不会出现杂散光的射出影响显示，从而提高了显示面板的开口率。
在一种实施例中，在使得遮光图案对相邻色阻之间的区域进行遮光时，考虑到更好的遮光性，可以使得遮光图案的宽度大于相邻色阻之间的间距，由于遮光图案是在人眼侧进行遮光，因此，即使遮光图案的宽度大于相邻色阻之间的间距，但是相较于黑色矩阵在发光侧进行遮光，遮光图案的宽度小于黑色矩阵的宽度，从而提高了液晶显示面板的开口率，在遮光图案的宽度等于相邻色阻之间的间距时，遮光图案的遮光效果与黑色矩阵的遮光效果相同甚至更好，此处设置遮光图案的宽度大于相邻色阻之间的间距，是考虑到在需要更好的遮光性时，可以略微提高遮光图案的宽度，但仍然能够提高显示面板的开口率，提高显示面板的显示效果。
在一种实施例中，在使得遮光图案对相邻色阻之间进行遮光时，考虑到在遮光图案宽度小于相邻色阻之间的间距时，在一定范围内，不会影响到显示效果，则可以使得遮光图案的宽度小于相邻色阻之间的间距，从而进一步提高显示面板的开口率，但此时由于露出的相邻色阻之间的间距透出的光线不影响显示面板的显示效果，因此，在对显示装置的相邻色阻之间的区域进行遮光的同时，提高了显示装置的开口率。
在一种实施例中，所述遮光图案的材料包括无机非金属材料，具体的，选择遮光性较好的无机非金属材料作为遮光图案的材料，从而提高液晶显示面板的相邻像素之间的区域的遮光性。
在一种实施例中，所述遮光图案的材料包括铜、铝、银、锌、铜锌叠层、铜钛叠层和铜铝叠层中的一种，通过使得遮光图案的材料为金属或者合金或者金属叠层，则可以使得金属对光线进行反射和吸收，从而避免光线射出，且由于遮光图案的材料为金属，金属具有延展性，则对于需要弯曲或者弯折的液晶显示面板，不影响显示面板的弯折性能，同时，由于金属能够导出静电，且本申请实施例将金属设置基板外，则可以通过金属释放静电，从而提高液晶显示面板的防静电能力，且在使用金属作为遮光图案的材料时，由于金属材料与基板的附着力较好，因此，相较于采用有机材料会出现溶结和剥离的问题，采用金属材料的遮光图案不会出现剥离和脱离。
在一种实施例中，在采用金属材料作为遮光图案的材料时，由于金属材料设置于基板外，而液晶显示面板的静电是由于搬运或者移动过程中的摩擦导致，会出现在液晶显示面板的基板外，因此，将遮光图案设置在液晶显示面板的基板外，可以使得金属材料直接将静电导出，从而避免液晶显示面板出现静电集中，提高液晶显示面板的防静电能力。
在一种实施例中，所述遮光图案与所述第一衬底贴合设置，即通过将遮光图案设置在第一衬底上，通过将遮光图案的厚度设置为较薄，从而可以提高液晶显示面板的开口率，且避免遮光图案出现脱落。
在一种实施例中，所述遮光图案的厚度范围为100埃至1000埃，将遮光图案的厚度设置的较薄，避免增加液晶显示面板的厚度，但本申请实施例不限于此，能够对像素之间的区域进行遮光的厚度均可以作为遮光图案的厚度值。
在一种实施例中，如图4所示，所述液晶显示面板还包括平坦层25，所述平坦层25设置于所述色阻对应区域，且所述平坦层25设置于所述遮光图案241形成的空隙242内，即在设置遮光图案时，考虑到会在遮光图案上设置其他膜层或者其他结构，因此，需要使得遮光图案的平坦，从而便于其他膜层的设计，因此，在设计遮光图案后，考虑到遮光图案会存在一定的空隙，因此，可以在空隙内设置平坦层，从而使得平坦层填补遮光图案的空隙，使得遮光层保持平整。
在一种实施例中，所述遮光层的厚度与所述平坦层的厚度相等，即在设置平坦层时，仅需要使得平坦层的厚度与遮光层的厚度一致，从而使得遮光层保持平整，便于后续的膜层的形成。
在一种实施例中，所述平坦层的厚度大于所述遮光层的厚度，即在形成平坦层时，使得平坦层设置在遮光图案的空隙内，同时，平坦层设置在遮光图案上，从而使得在形成遮光图案后，平坦层使得液晶显示面板保持平整，在设计其他膜层或者其他结构时，避免存在不平整的区域导致其他膜层或者其他结构无法完整形成或者出现弯曲，影响显示。
在一种实施例中，所述平坦层的材料包括无机材料，具体的，平坦层的材料包括氮化硅、氧化硅、氮氧化硅中的一种，即在设置平坦层时，考虑到平坦层设置在色阻对应区域，因此，采用无机材料形成平坦层，从而提高平坦层的透光性。
在一种实施例中，平坦层的材料包括无机材料，遮光图案的材料包括铜、铝、银、锌、铜锌叠层、铜钛叠层和铜铝叠层中的一种，即采用无机材料形成平坦层时，考虑到无机材料的弯折性能较差，因此采用金属或者金属叠层形成遮光图案，从而使得无机材料被分割，而金属具有较好的延展性能，因此，在液晶显示面板需要进行弯折或者弯曲时，由于金属材料的存在，平坦层不会影响到液晶显示面板的弯折性能。
在一种实施例中，平坦层的材料包括有机材料，即在为了提高液晶显示面板的弯折性能，可以使得平坦层的材料为有机材料，从而提高平坦层和遮光层的柔性，同时，考虑到平坦层设置于色阻对应区域，因此，需要使得平坦层的透光性较好，从而可以选择透光性较好的有机材料作为平坦层的材料。
在一种实施例中，如图2至图4所示，所述液晶显示面板还包括色阻平坦层233，所述色阻平坦层设置于所述色阻之间，即在形成色阻层时，由于在色阻层由红色色阻232a，蓝色色阻232b，绿色色阻232c组成，各个色阻之间存在一定的间距，在本申请实施例中，在相邻色阻之间未设置黑色矩阵，因此，需要使得色阻层保持平坦，因此，可以在色阻之间设置色阻平坦层，从而使得色阻层保持平坦，在后续形成公共电极层以及其他膜层时，保持其他膜层的平坦。
在一种实施例中，色阻平坦层的材料与公共电极层的材料相同，公共电极层填充至所述色阻相邻区域，即在对色阻层进行平坦化时，可以使得公共电极层直接填充至色阻之间的区域，从而直接在色阻层上形成公共电极层，使得色阻层保持平坦的同时，公共电极层也保持平坦，同时，由于公共电极层的厚度增加，从而可以降低公共电极层的阻抗，提高液晶显示面板的显示效果。
在一种实施例中，色阻平坦层的材料与所述色阻层的材料相同，即在形成色阻平坦层时，可以使得相邻色阻之间接触，然后对相邻色阻之间的区域进行遮光，从而使得在色阻正常发光的同时，遮光图案对色阻之间的区域进行遮光，从而提高了液晶显示面板的开口率。
在一种实施例中，色阻平坦层的材料包括无机材料，即在设置色阻平坦层的材料时，也可以采用无机材料形成色阻平坦层，从而使得色阻平坦层将色阻层平坦化。
在一种实施例中，所述第一基板包括第三衬底、驱动电路层和色阻层，相邻色阻搭接设置，所述遮光图案设置于所述第三衬底远离所述驱动电路层的方向上，即在采用COA（Color On Array，彩色滤光片设置在阵列基板上）基板的液晶显示面板中，通过在第三衬底下设置遮光图案，使得遮光图案对相邻像素进行遮光，从而提高具有COA基板的液晶显示面板的开口率。
在一种实施例中，所述第一基板包括第三衬底、驱动电路层和色阻层，相邻色阻搭接设置，第二基板包括第二衬底和设置于第二衬底上的公共电极层，所述遮光图案设置于第二衬底远离所述公共电极层的方向上，即考虑到具有COA基板的液晶显示面板会从第二基板侧发射出去，则可以在第二基板外设置遮光图案，无需设置黑色矩阵，从而提高液晶显示面板的开口率。
如图3、图5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，所述液晶显示面板包括第一基板21、第二基板23和液晶层22，所述第二基板23与所述第一基板21相对设置，所述液晶层22设置于所述第一基板21与所述第二基板23之间，其中，在所述第一基板21远离所述液晶层22的方向上设有遮光层24，所述遮光层24图案化形成有遮光图案241，所述遮光图案241设置于相邻像素之间，且遮光图案241的宽度c2（d2）与相邻像素之间的间距c1（d1）的差值小于或者等于阈值k，所述遮光图案241的材料包括无机材料；
偏光片31，设置于所述液晶显示面板外。
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和偏光片，该液晶显示面板通过第一基板远离液晶层的方向设置遮光层，遮光层图案化形成有遮光图案，并使得遮光图案设置于相邻像素之间，且遮光图案的宽度与相邻像素之间的间距的差值小于或者等于阈值，遮光图案的材料包括无机材料，从而使得通过遮光图案对相邻像素之间的区域进行遮光，无需设置黑色矩阵，提高对液晶的控制能力，且由于遮光图案设置在基板外，从而对人眼侧进行遮光，无需使得遮光图案的宽度大于相邻像素之间的间距，从而提高了液晶显示面板的开口率。
在一种实施例中，如图5所示，所述偏光片31包括第一偏光片312和第二偏光片311，所述第一偏光片312设置于靠近所述第一基板21的一侧，所述第二偏光片311设置于靠近所述第二基板23的一侧，所述第一偏光片312与第一基板21之间和所述第二偏光片311与第二基板23之间的至少一个设有遮光图案241，即在设置遮光图案时，在液晶显示面板与偏光片之间设置遮光图案，使得在光线穿过液晶显示面板后，遮光图案对相邻像素之间的区域的光线进行遮光，从而无需设置黑色矩阵，从而提高液晶显示面板的开口率。
在一种实施例中，在本申请实施例中，考虑到光线会从一侧发射出去，因此，在上述实施例中，仅会在从液晶显示面板的光线射出的一侧设置遮光图案，从而避免光线被遮挡，且避免液晶显示面板的厚度较大，但在实际过程中，在需要在液晶显示面板的两侧设置遮光图案时，也可以在液晶显示面板的两侧形成遮光图案。
在一种实施例中，液晶显示装置还包括背光模组，所述背光模组设置于所述偏光片远离所述液晶显示面板的方向上，即本申请实施例中的液晶显示装置可以是采用背光模组的液晶显示装置，但本申请实施例不限于此，例如采用mini LED（迷你发光二极管）、micro LED（微型发光二极管）作为光源设置在阵列基板的液晶显示面板，也可以采用遮光图案进行遮光，从而提高液晶显示装置的开口率。
在一种实施例中，在形成遮光图案时，可以先在基板的衬底上形成遮光图案，从而在后续形成其他膜层时，即使摩擦产生静电，也可以通过遮光图案将静电进行释放，从而避免液晶显示面板中出现静电积累，提高液晶显示面板的防静电能力。
在一种实施例中，在液晶显示装置中，所述第一基板包括阵列基板，所述阵列基板包括第一衬底和设置于所述第一衬底上的驱动电路层，所述遮光图案设置于所述第一衬底远离所述驱动电路层的方向上。
在一种实施例中，在液晶显示装置中，所述第一基板包括彩膜基板，所述彩膜基板包括第二衬底和设置于所述第二衬底上的色阻层，相邻色阻间隔设置，所述遮光图案设置于所述第二衬底远离所述色阻层的方向上。
在一种实施例中，在液晶显示装置中，所述遮光图案包括横向设置的第一图案与纵向设置的第二图案，所述第一图案的宽度与横向设置的相邻色阻的间距相等，所述第二图案的宽度与纵向设置的相邻色阻的间距相等。
在一种实施例中，在液晶显示装置中，所述遮光图案的材料包括铜、铝、银、锌、铜锌叠层、铜钛叠层和铜铝叠层中的一种。
在一种实施例中，在液晶显示装置中，所述液晶显示面板还包括平坦层，所述平坦层设置于所述色阻对应区域，且所述平坦层设置于所述遮光图案形成的空隙内。
在一种实施例中，在液晶显示装置中，所述平坦层的材料包括氮化硅、氧化硅、氮氧化硅中的一种。
在一种实施例中，在液晶显示装置中，所述第一基板包括第三衬底、驱动电路层和色阻层，相邻色阻搭接设置，所述遮光图案设置于所述第三衬底远离所述驱动电路层的方向上。
在一种实施例中，在液晶显示装置中，所述液晶显示面板包括端子区，所述遮光图案沿着垂直于端子区和端子区相对的区域的方向设置。
根据以上实施例可知：
本申请实施例提供一种液晶显示面板和液晶显示装置，该液晶显示面板包括第一基板、第二基板和液晶层，第二基板与第一基板相对设置，液晶层设置于第一基板与第二基板之间，其中，在第一基板远离液晶层的方向上设有遮光层，遮光层图案化形成有遮光图案，遮光图案设置于相邻像素之间，且遮光图案的宽度与相邻像素之间的间距的差值小于或者等于阈值，遮光图案的材料包括无机材料；本申请实施例通过在第一基板远离液晶层的方向设置遮光图案，且遮光图案设置于相邻像素之间，遮光图案的宽度与相邻像素之间的间距的差值小于或者等于阈值，即使得通过在液晶显示面板的基板外设置遮光层，通过将遮光层设置于相邻像素之间，从而使得遮光层对相邻像素之间的光线进行遮挡，无需设置黑色矩阵，提高对液晶的控制能力，由于遮光层设置于液晶显示面板的基板外，因此，直接在人眼侧对杂散光进行遮挡，无需使得遮光图案的宽度大于相邻像素之间的间距，从而提高了液晶显示面板的开口率。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
