下面结合附图和较佳的实施例对本公开作进一步详细说明。
图1是本公开的一实施例的液晶显示面板的局部剖面示意图。液晶显示装置可包括液晶显示面板100和背光模块(未绘示)。液晶显示面板100相对于背光模块来设置，此背光模块可为侧光式(side Lighting)背光模块或直下式入光(Bottom Lighting)背光模块，以提供背光至液晶显示面板100。液晶显示面板100可为VA型液晶显示面板。
如图1所示，液晶显示面板100可包括第一基板110、第二基板120、液晶层130、第一偏光片140、第二偏光片150、相位差片160及170。液晶层130是形成于第一基板110及第二基板120之间，亦即液晶层130是位于第一基板110及第二基板120的内侧。第一偏光片140是设置于第一基板110的外侧，第二偏光片150是设置于第二基板120的外侧，相位差片160是设置于第一基板110与第一偏光片140之间，相位差片170是设置于第二基板120与第二偏光片150之间。
如图1所示，第一基板110及第二基板120的基板材料可为玻璃基板或可挠性塑料基板。值得注意的是，在本公开的实施例中，彩色滤光片和主动开关(例如TFT)阵列可配置在同一基板上。
下面参考图2至图5描述本公开实施例的显示面板结构示意图。所述显示面板包括第一基板和第二基板，所述第一基板和所述第二基板之间设置有多个支撑所述第一基板和所述第二基板的间隔单元(Photo Space)1，所述间隔单元1间隔设置，所述间隔单元包括至少两个具有断差的第一间隔单元和第二间隔单元。两个所述间隔单元1之间有断差，避免按压时造成影像暗纹而影响成盒的品质，提升了显示效果，面板显示品味更好，使用者能得到更好的观赏体验，同时节省成本，提升产品竞争力。
作为本公开的又一个实施例，显示面板还包括黑矩阵(Black Matrix)2，所述黑矩阵2设置在所述第一基板与所述间隔单元1之间，所述黑矩阵2在对应两个所述间隔单元1位置形成高度差，对应地，两个所述间隔单元1之间有断差。在黑矩阵2上形成多种黑矩阵2高度，让对应的间隔单元形成断差，避免按压时造成影像暗纹，影响成盒的品质。
具体的，如图2所示为本公开一个实施例的显示面板的结构示意图，通过半色调掩膜工艺(Half Tone Mask)所述黑矩阵2在对应相邻两个所述间隔单元1位置形成高度差，对应地，相邻两个所述间隔单元1之间有断差。将断差形成于相邻的两个间隔单元1之间，充分利用断差的均匀设置，增大液晶边距，有 效避免影像暗纹的形成，保证显示面板的质量。当然断差除了形成于相邻的两个间隔单元1也可以间隔存在于所述间隔单元1之间，间隔的距离可以是均匀或按其他特定序列的。其中断差的差值可以是定值也可以存在变化。
其中，所述黑矩阵2在对应相邻两个所述间隔单元1位置通过半色调掩膜工艺形成所述高度差。采用灰色光罩或半色调掩膜工艺(Half Tone Mask)，把两道上曝光工艺完成的工序合并为一个，节省一道曝光工序，缩短了生产周期，提高了生产效率，降低了生产成本，提高了市场竞争能力。灰色光罩或半色调掩膜工艺(Half Tone Mask)利用了光栅的部分透光性，可以将PR(光阻)不完全曝光。半透膜部分按所需要钝化层的高度差来决定光线透过的多少，一般情况下光线透过率是正常部分的35％左右。
如图3所示，作为本公开的又一个实施例，所述第一基板还包括第一玻璃基板3，所述第一玻璃基板3在对应所述第一间隔单元或第二间隔单元位置向内设置有凸部31，利用所述凸部31在对应两个所述间隔单元位置形成高度差，对应地，两个所述间隔单元之间有断差。利用第一玻璃基板3上凸部31的结构，凸部31设置简单，让对应的间隔单元(PS)1形成断差，避免按压时造成影像暗纹，影响成盒的品质。当然，所述第一玻璃基板3可以在对应所述第一间隔单元和第二间隔单元位置都向内设置有凸部31，但两个间隔单元1对应的凸部31高度不同。
具体的，所述凸部31在对应相邻两个所述间隔单元1位置形成高度差，对应地，相邻两个所述间隔单元1之间有断差。将断差形成于相邻的两个间隔单元1之间，充分利用断差的均匀设置，增大液晶边距，有效避免影像暗纹的形成，保证显示面板的质量。当然断差除了形成于相邻的两个间隔单元1也可以间隔存在于所述间隔单元1之间，间隔的距离可以是均匀或按其他特定序列的。其中断差的差值可以是定值也可以存在变化。
具体的，如图3所示为本公开一个实施例的显示面板的结构示意图，相邻两个所述凸部31中的一个所述凸部31的高度为0。第一玻璃基板3上对应相邻 两个所述间隔单元1位置一处不做变化，一处利用凸部31的高度共同使间隔单元1形成断差。
更具体地，所述液晶显示面板的第二基板可包括主动开关阵列及彩色光阻层，所述彩色光阻层是形成于所述主动开关阵列上。液晶层是形成于所述第一基板及第二基板之间。多个间隔单元1是设置于所述第一基板和所述第二基板之间，部分的所述间隔单元1是对位于所述彩色光阻层及所述凸部31之间，以支撑所述第一基板和所述第二基板。另一部分的间隔单元1则未对位于所述彩色光阻层及所述凸部31之间，因而形成断差于这些间隔单元1之间。
在一些实施例中，多个间隔单元1的长度可相同，而利用凸部31来形成断差。因此，间隔单元1可不需使用特别的光罩(例如Half Tone Mask)来形成，而降低成本。
在一些实施例中，多个间隔单元的长度是略小于所述彩色光阻层及所述凸部之间的距离。因此，部分的间隔单元1可支撑于彩色光阻层及所述凸部之间。
在一些实施例中，所述第一基板包括玻璃基板，所述凸部是一体形成于所述玻璃基板上。
作为本公开的又一个实施例，所述第二基板还包括第二玻璃基板4和彩色光阻层，所述彩色光阻层设置在所述第二玻璃基板4与所述间隔单元1之间，所述彩色光阻层在对应两个所述间隔单元1位置形成高度差，对应地，两个所述间隔单元1之间有断差。在彩色光阻层上形成多种彩色光阻高度，间隔单元(PS)1制作在彩色光阻上，当间隔单元(PS)1成形后利用地形上的优势形成断差，避免按压时造成影像暗纹，影响成盒的品质。
具体的，所述彩色光阻层在对应相邻两个所述间隔单元1位置形成高度差，对应地，相邻两个所述间隔单元1之间有断差。将断差形成于相邻的两个间隔单元1之间，充分利用断差的均匀设置，增大液晶边距，有效避免影像暗纹的形成，保证显示面板的质量。当然断差除了形成于相邻的两个间隔单元1也可以间隔存在于所述间隔单元1之间，间隔的距离可以是均匀或按其他特定序列 的。其中断差的差值可以是定值也可以存在变化。
具体的，如图4所示为本公开一个实施例的显示面板的结构示意图，彩色光阻层包括R光阻51、G光阻52、B光阻，两处相邻的G光阻52通过半色调掩膜工艺(Half Tone Mask)形成高度差，相应地，设置在G光阻52和B光阻53上的间隔单元1之间形成断差，有效的解决影像暗纹问题。
具体的，所述彩色光阻层在对应相邻两个所述间隔单元1位置过半色调掩膜工艺形成所述高度差。采用灰色光罩或半色调掩膜工艺(Half Tone Mask)，把两道上曝光工艺完成的工序合并为一个，节省一道曝光工序，缩短了生产周期，提高了生产效率，降低了生产成本，提高了市场竞争能力。半色调掩膜工艺(Half Tone Mask)利用了光栅的部分透光性，可以将PR(光阻)不完全曝光。半透膜部分按所需要钝化层的高度差来决定光线透过的多少，一般情况下光线透过率是正常部分的35％左右。
更具体地，第二基板可包括主动开关阵列及彩色光阻层，所述彩色光阻层是形成于所述主动开关阵列上，所述彩色光阻层包括多个不同颜色的光阻51、52、53，至少部分的所述光阻具有不同的高度，例如图4中的光阻52可具有不同的高度。其中，至少部分的所述光阻是利用灰色光罩或半色调光罩来形成，以形成不同高度的所述光阻。
更具体地，液晶显示面板的制造方法可包括：
提供第一基板及第二基板；
形成主动开关阵列于所述第二基板上；
依序形成多个不同颜色的光阻于所述第二基板上，以形成彩色光阻层，其中至少部分的所述光阻是利用灰色光罩或半色调光罩来形成，以形成不同高度的所述光阻；
设置多个间隔单元于所述彩色光阻层上；以及
形成液晶层于所述第一基板及所述第二基板之间。
在一些实施例中，相同颜色的所述光阻具有不同的高度，例如光阻52可具 有第一高度及第二高度，第一高度不同于第二高度，所述第一高度及所述第二高度之间的高度差大于或等于0.5um。
在一些实施例中，不同颜色的所述光阻具有不同的高度，例如光阻51具有第一高度，光阻52具有第二高度，第一高度不同于第二高度，所述第一高度及所述第二高度之间的高度差大于或等于0.5um。
在一些实施例中，多个间隔单元1的长度可相同，而利用不同高度的光阻51、52、53来形成断差。因此，间隔单元1可不需使用特别的光罩(例如Half Tone Mask)来形成，而降低成本。
作为本公开的又一个实施例，所述第二基板还包括第二玻璃基板4和彩色光阻层，所述彩色光阻层设置在所述第二玻璃基板4与所述间隔单元1之间，所述彩色光阻层与所述间隔单元1之间设置有保护层7，所述保护层7在对应两个所述间隔单元1位置形成高度差，对应地，两个所述间隔单元1之间有断差。间隔单元(PS)1下方的保护层7厚度不一，间隔单元(PS)1制作在保护层7上，当间隔单元(PS)1成形后利用地形上的优势形成断差，避免按压时造成影像暗纹，影响成盒的品质。
具体的，所述保护层7在对应相邻两个所述间隔单元1位置形成高度差，对应地，相邻两个所述间隔单元1之间有断差。将断差形成于相邻的两个间隔单元1之间，充分利用断差的均匀设置，增大液晶边距，有效避免影像暗纹的形成，保证显示面板的质量。当然断差除了形成于相邻的两个间隔单元1也可以间隔存在于所述间隔单元1之间，间隔的距离可以是均匀或按其他特定序列的。其中断差的差值可以是定值也可以存在变化。
具体的，对应所述间隔单元1位置的所述彩色光阻层之间等高；所述第一间隔单元与对应彩色光阻层之间设有导电层；所述第二间隔单元与对应彩色光阻层之间设有导电层和保护层。直接将对应间隔单元(PS)1下方的保护层7挖掉，形成断差，步骤简单。其中所述第二基板上还设有薄膜晶体管6；所述第一间隔单元和第二间隔单元分别设置相邻两个所述薄膜晶体管6上方位置。薄 膜晶体管6为如图所示几个多边形堆叠组成物，导电层8与薄膜晶体管6中的漏极相连。其中，两个间隔单元1对应的彩色光阻层颜色不同.
具体的，除了可仅挖掉对应位置的保护层7使间隔单元1之间形成断差外，也可以结合通过半色调掩膜工艺(Half Tone Mask)处理彩色光阻形成高度差的方式做更充分的断差形成。如图5所示为本公开一个实施例的显示面板的结构示意图，彩色光阻层包括R光阻51、G光阻52、B光阻，两处相邻的G光阻52通过半色调掩膜工艺(Half Tone Mask)形成高度差，同时挖掉一处G光阻52下方的保护层7，相应地，设置在G光阻52和B光阻53上的间隔单元1之间形成断差，有效的解决影像暗纹问题。
更具体地，保护层7是形成于所述彩色光阻层上，其中至少部分的所述保护层7是被移除(如图5所示)，至少部分的所述间隔单元是设置于所述保护层被移除的部分区域上，以形成高度差于间隔单元1之间。
在一些实施例中，通过至少部分的所述保护层7被移除，所述保护层7可具有不同的厚度，以形成高度差于间隔单元1之间。
在一些实施例中，所述保护层7被移除的部分区域上暴露出部分的所述所述彩色光阻层。具体地，保护层7被移除的部分区域上可暴露出部分的所述所述彩色光阻层，使得透明导电层8直接接触于彩色光阻层的部分光阻。
在一些实施例中，所述多个间隔单元的长度相同，而利用保护层7的移除来形成断差。因此，间隔单元1可不需使用特别的光罩(例如Half Tone Mask)来形成，而降低成本。
在一些实施例中，所述保护层7被移除的部分区域面积是小于所述保护层7的全部区域面积的10％，以避免影响保护层7的正常保护功能。
更具体地，液晶显示面板的制造方法可包括：
提供第一基板及第二基板；
形成主动开关阵列于所述第二基板上；
形成彩色光阻层于所述第二基板上；
形成保护层于7所述彩色光阻层上；
移除部分的保护层7；
设置多个间隔单元1于所述保护层7上，其中至少部分的所述间隔单元是设置于所述保护层被移除的部分区域上；以及
形成液晶层于所述第一基板及所述第二基板之间。
作为本公开的又一个实施例，所述第一间隔单元和所述第二间隔单元与所述第一基板的接触面存在高度差；所述第一间隔单元和所述第二间隔单元与所述第二基板的接触面存在高度差；对应地，两个所述间隔单元1之间有断差。两个基板方向均存在断差，可以增加断差，方便整个显示面板制成顺利，防止因断差值有限而影响显示面板的显示效果。
具体的，如图6所示为本公开一个实施例的显示面板的结构示意图，第一玻璃基板3在对应的一个间隔单元1位置形成凸部31，第二玻璃基板4在对应的一个间隔单元1位置形成凸部31，从而两个间隔单元1形成更大差值的断差。当然除了通过玻璃基板向内设置凸部31的方式，还可以是其他的，第一基板一侧和第二基板一侧采用的方式也可以不同。
每个所述间隔单元1内的光起始剂相同。在不同间隔单元1内设置相同的光起始剂，在不同波长光线照射下使得不同间隔单元1产生不同程度的交联反应，进而使得不同间隔单元1形成不同程度的收缩量，这样就实现了不同间隔单元1具有断差。采用不同波长光线照射相同的光起始剂和间隔单元1上，通过不同波长光线的作用来控制不同间隔单元1产生不同程度的交联反应，进而控制不同间隔单元1的收缩量，其控制效果好，使得不同间隔单元1之间的断差达到预设的需求。另外，这样设置在生产工艺上，无需对不同的间隔单元1进行不同的设置，其设置简单。
如图7所示为本公开一个实施例的光阻及保护层的结构示意图，在一些实施例中，所述彩色光阻层设有光阻凹部521，所述保护层7被移除的区域是形成于所述光阻凹部521上，亦即光阻凹部521内没有保护层7，以形成更大差值的 断差于间隔单元1之间。
具体的，所述黑矩阵(Black Matrix)2和第二间隔单元等高设置，所述第一间隔单元高于所述第二间隔单元，所述第二间隔单元位于所述第一间隔单元和黑矩阵2之间。将第一间隔单元设置高于第二间隔单元及黑矩阵2将第二间隔单元设置和黑矩阵2等高，第一间隔单元、第二间隔单元及黑矩阵2的高度控制更好，也就是对断差的控制效果更好，使得显示面板的显示效果更好。
所述第一间隔单元和第二间隔单元之间的断差值大于或等于0.5um，具体的是，第一间隔单元的高度H1和第二间隔单元的高度H2之间的高度差大于或等于0.5um。当第一间隔单元和第二间隔单元之间的断差值小于0.5um时，对显示面板的显示影响大，并影响其他制程，增加了整个显示面板的难度。通过不同波长光线与光起始剂的配合作用来控制不同间隔单元之间的收缩量，实现对第一间隔单元和第二间隔单元之间断差的控制大于或等于0.5um，就方便整个显示面板制成顺利，防止因断差值有限而影响显示面板的显示效果。
根据本公开的另一个方面，本公开还公开了一种显示装置，所述显示装置包括背光模组和如上所述的显示面板。
作为本公开的再一个实施例，本实施例公开了一种显示装置的背光模组和显示面板。关于显示面板的具体结构和连接关系可参见图1至图4，在此不再一一详述。
以上内容是结合具体的优选实施方式对本公开所作的进一步详细说明，不能认定本公开的具体实施只局限于这些说明。对于本公开所属技术领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本公开的保护范围。
