【附图说明】
图1是本申请显示面板一实施例的结构示意图；
图2是本申请显示面板另一实施例的结构示意图；
图3是本申请显示面板又一实施例的结构示意图。
【具体实施方式】
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施方式中也可以实现本申请。在其它情况中，省略对众所周知的装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
参阅图1，图1是本申请显示面板一实施例的结构示意图。本申请显示面板应用于液晶显示装置。
显示面板包括上偏光片110、下偏光片120、在上偏光片110和下偏光片120之间相对设置的第一基板130和第二基板140、夹持在第一基板130和第二基板140之间的液晶层（图未示），显示面板还包括量子点层150以及量子点层的保护层160。
其中，第一基板130为彩色滤光片（Color Filter，CF）基板，第二基板140为阵列基板。
量子点层150设置于第二基板140远离液晶层的一侧，量子点层的保护层160设置于量子点层150与下偏光片120之间。
上偏光片110与下偏光片120相对设置，且大小、形状相同，上偏光片110或下偏光片120在第二基板140上的投影区域也相同。量子点层150覆盖第二基板140的面积至少不小于下上偏光片110或偏光片120在第二基板140上的投影区域。
当上偏光片110或下偏光片120在第二基板140上的投影区域不相同时，量子点层150覆盖第二基板140的面积至少不小于下上偏光片110或偏光片120在第二基板140上较大的投影区域。
量子点层150用于在光源的作用下发射三原色光并过滤掉除三原色以外的其他光，以补偿光源中的三原色光的色域，其中，三原色光包括红光、绿光、蓝光。
量子点层的保护层160用于防止量子点层150被水或空气氧化。
上述方案，通过在显示面板的第二基板远离液晶层的一侧设置量子点层，以及在量子点层远离第二基板的一侧设置量子点层的保护层，能够提高显示色域值，从而改善显示效果。
请参阅图2，图2是本申请显示面板另一实施例的结构示意图。
显示面板包括上偏光片110、下偏光片120、在上偏光片110和下偏光片120之间相对设置的第一基板130和第二基板140、夹持在第一基板130和第二基板140之间的液晶层（图未示），显示面板还包括量子点层150以及量子点层的保护层260。
其中，第一基板130为彩色滤光片（Color Filter，CF）基板，第二基板140为阵列基板。
量子点层150设置于第二基板140远离液晶层的一侧，量子点层的保护层260设置于量子点层150与下偏光片120之间。
量子点层的保护层260用于防止量子点层150被水或空气氧化。
其中，量子点层150通过涂布的方式覆盖在第二基板140远离液晶层的一侧。量子点层的保护层260为水氧隔绝保护层，量子点层的保护层260通过水氧隔绝双面胶固定，但并不限于此，还可以通过其他方式固定。量子点层的保护层260的材料可以为聚对苯二甲酸乙二醇酯（PET），但并不限于此，还可以选用其他具有水氧隔绝功能的材料。
由于第一基板130不小于上偏光片110以及下偏光片120，因此，量子点层150可以完全覆盖第二基板140远离液晶层的一侧，量子点层的保护层260覆盖量子点层150远离第二基板140的一侧，且量子点层的保护层260还覆盖量子点层150的侧面以及第二基板140相对平行的侧面（即，垂直于液晶层的侧面），以防止量子点层150的边缘被氧化。
在其他实施例中，量子点层150以及量子点层的保护层260还可以设置为其他形式，例如，量子点层150可以完全覆盖第二基板140远离液晶层的一侧，量子点层的保护层260覆盖量子点层150远离第二基板140的一侧以及量子点层150的侧面，使得量子点层的保护层260完全覆盖量子点层150，此处不作限制。
量子点层150在光源的作用下发射三原色光并过滤掉除三原色以外的其他光，发射出高色域的白光，以补偿光源中的三原色光的色域，其中，三原色光包括红光、绿光、蓝光。
其中，量子点是具有比散装（bulk）激子玻尔半径小的直径的纳米晶体。量子点（“QD”，也被称为半导体纳米晶体）可以在光源的照射下发射可见光或红外区域中的光。由于量子局限效应，量子点的电子态之间的能量差是量子点的组分和物理尺寸二者的函数，因此，可以通过改变量子点的物理尺寸来调谐和调整量子点的光学和光电子学属性。
量子点具有吸收比吸收峰值波长更短的所有波长，并发射更长波长处的光的特性。例如，直径为2nm的量子点在光源的作用下发射蓝色光，直径为10nm的量子点在光源的作用下发射红色光。
量子点层150补偿显示色域值的能力与组成量子点层150中量子点的直径以及不同直径的量子点的混合比例有关。
量子点层150至少由三种直径的量子点按预设比例混合而成，其中，每种直径对应一种三原色光，预设比例由显示面板的光源中三原色光的光谱峰值确定。即，量子点层150中量子点的直径至少包括能够发射三原色光对应的直径，不同直径的量子点的混合比例则根据光源中三原色光的光谱的峰值而确定。
当光源中三原色光中任意一种光的光谱的峰值比较低时，可以增大将该种光对应直径的量子点所占的比例。当然，并不限于此，还可以将光源中三原色光的光谱的峰值和预期色域值对应的三原色光的光谱峰值进行比较，分别计算它们之间的差值，并根据三种光的差值确定混合比例。
由于光源不同，使得光源中三原色的光谱峰值不同，不同直径的量子点的混合比例也会有所不同，可以根据实际情况设置不同直径的量子点的混合比例调整色域值，以获得较佳的显示效果。
上述方案，通过在显示面板的第二基板远离液晶层的一侧设置量子点层，以及在量子点层远离第二基板的一侧设置量子点层的保护层，能够提高显示色域值，从而改善显示效果。
量子点层的保护层完全覆盖量子点层，能够防止量子点层的边缘被氧化，从而能够防止因量子点层被氧化而导致色域值降低，显示效果变差的情况。
请参阅图3，图3是本申请显示面板又一实施例的结构示意图。本实施例与图2对应的实施例的不同之处在于，量子点层350以及量子点层的保护层360的设置方式。
具体为：量子点层350的覆盖面积小于第二基板140远离液晶层的一侧的面积，且大于或等于上偏光片110或下偏光片120在第二基板140上的投影区域的面积；量子点层的保护层360的覆盖面积等于第二基板140远离液晶层的一侧的面积。
鉴于第二基板140的厚度有一定的限制，量子点层的保护层360贴于第二基板140垂直于液晶层的侧面时可靠性不好，因此，量子点层150没有完全覆盖第二基板140，以留出一定空间贴合量子点层的保护层160，这样可以更好地防止量子点层150，保持具有较高色域的显示效果。
在本实施例中，量子点层150部分覆盖第二基板140远离液晶层的一侧，量子点层350的覆盖面积小于第二基板140远离液晶层的一侧的面积，且大于或等于上偏光片110或下偏光片120在第二基板140上的投影区域的面积，或者当上偏光片110或下偏光片120在第二基板140上的较大投影区域不同时，大于或等于上偏光片110或下偏光片120在第二基板140上的较大投影区域的面积。
量子点层的保护层360安全覆盖量子点层350，其覆盖面积等于第二基板140远离液晶层的一侧的面积。
上述方案，通过在显示面板的第二基板远离液晶层的一侧设置量子点层，以及在量子点层远离第二基板的一侧设置量子点层的保护层，能够提高显示色域值，从而改善显示效果。由于量子点层的保护层完全覆盖量子点层，能够防止量子点层的边缘被氧化，从而能够防止因量子点层被氧化而导致色域值降低，显示效果变差的情况。
本申请还提供一种液晶显示装置，液晶显示装置包括上述任一实施例所述的显示面板。
以上描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施方式中也可以实现本申请。在其它情况中，省略对众所周知的装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
