技术领域
本申请涉及显示领域，特别是涉及一种阵列基板、显示面板及显示装置。
背景技术
LCD(Liquid Crystal Display，液晶显示器)是目前应用比较广泛的一种平板显示器，随着显示技术的发展，LCD面板的尺寸也越来越大。
目前大尺寸显示面板多半采用负型VA(Vertical Alignment，垂直配向)液晶或IPS(In-Plane Switching，平面转换)液晶技术。相较于IPS液晶技术来说，VA型液晶技术存在生产效率较高及制造成本低的优势，但相较于IPS液晶技术来说，VA型液晶技术存在较明显的光学性质缺陷。尤其是在商业应用方面，大尺寸面板需要较大的视角呈现，而VA型液晶驱动在视角色偏方面往往无法符合市场应用需求。例如，在侧视角下，随着电压增加，蓝像素子单元的亮度饱和的趋势比红、绿两种像素子单元来得显著及快速，使得侧视角观察画质会呈现偏蓝色偏的明显缺陷。
一般VA型液晶技术解决视角色偏的方式是将RGB各子像素再划分为主/次(main/sub)像素，藉由对主次像素给予不同的驱动电压来解决视角色偏的缺陷，这样的像素设计往往需要再设计金属走线或TFT(Thin Film Transistor，薄膜晶体管)元件来驱动次像素，不仅牺牲可透光开口区、影响面板透率，还提升了背光成本。

具体实施方式
为了便于理解本申请，下面将参照相关附图对本申请进行更全面的描述。附图中给出了本申请的较佳实施方式。但是，本申请可以以许多不同的形式来实现，并不限于本文所描述的实施方式。相反地，提供这些实施方式的目的是使对本申请的公开内容理解的更加透彻全面。

例如，一种阵列基板，其包括衬底，所述衬底上设置有若干像素区域，每一所述像素区域内包括多个像素单元，每一所述像素单元包括红像素子单元、绿像素子单元及蓝像素子单元，所述蓝像素子单元上设置有蓝色光阻膜层，其中每一所述像素区域中相邻的两个蓝像素子单元具有不同厚度的蓝色光阻膜层。
例如，一种显示面板，其包括第一基板和第二基板，所述第一基板和所 述第二基板相对设置，所述第一基板为上述阵列基板。例如，所述第一基板包括衬底，所述衬底上设置有若干像素区域；每一所述像素区域内包括多个像素单元；每一所述像素单元包括红像素子单元、绿像素子单元及蓝像素子单元，所述蓝像素子单元上设置有蓝色光阻膜层；其中，每一所述像素区域中相邻的两个蓝像素子单元具有不同厚度的蓝色光阻膜层；可选地，所述第一基板上还形成有TFT阵列；或者，所述第二基板上形成有TFT阵列。
例如，一种显示装置，其包括数据接收芯片、显示面板及驱动板，其中显示面板包括如上所述的阵列基板，所述数据接收芯片与所述显示面板连接；所述驱动板包括时序控制电路，所述时序控制电路与所述数据接收芯片连接，所述时序控制电路用于：对各像素子单元的初始驱动电压信号进行处理，使处理后同一像素区域内同一行/列的多个蓝像素子单元的驱动电压相同；以及，向所述数据接收芯片发送处理后的驱动电压信号。
为了进一步理解上述阵列基板、显示面板及显示装置，下面将结合附图进行说明。请参阅图1，其为一实施例的阵列基板的结构示意图。该阵列基板10包括衬底11，所述衬底11上设置有若干像素区域110，每一所述像素区域内包括多个像素单元P，每一所述像素单元包括红像素子单元、绿像素子单元及蓝像素子单元，每一像素子单元上设置有光阻膜层，例如红像素子单元上设置有红色光阻膜层R，绿像素子单元上设置有绿色光阻膜层G，蓝像素子单元上设置有蓝色光阻膜层B。
具体地，每一所述像素区域中相邻的两个蓝像素子单元具有不同厚度的蓝色光阻膜层。例如，如图1所示，蓝色光阻膜层Bi+1，j和蓝色光阻膜层Bi， j+1的厚度分别与蓝色光阻膜层Bi，j的厚度不同；蓝色光阻膜层Bi，j+1和蓝色光阻膜层Bi+1，j的厚度分别与蓝色光阻膜层Bi+1，j+1的厚度不同。其中，Pi，j表示第i行第j列的像素单元，Bi，j表示第i行第j列的像素单元中蓝色光阻膜层。
在本实施例中，由于同一像素区域内相邻的两个蓝像素子单元的蓝色光阻膜层具有不同的膜厚，使得在同一像素区域内，蓝色光阻膜层与TFT基板之间存在不同的间隙距离，其中，光阻膜层与TFT基板之间的间隙距离又称 gap(间隙)值。各像素子单元的光学特性参数与gap值相关，例如，各像素子单元的相位延迟量与gap值相关，而相位延迟量的大小会影响光偏振态的变化，进而影响像素子单元的出光亮度。也就是说，在相同电压下，各像素子单元的出光亮度与gap值相关，且不同的像素子单元的出光亮度与gap值之间，存在不同的曲线关系。
本实施例中，由于同一像素区域内，多个蓝像素子单元存在多种gap值，使得侧视角下，同一像素区域内蓝像素子单元的光学特性随电压变化的曲线等效为多种gap值对应的曲线的平均值，从而使得侧视角混光下，蓝像素子单元的亮度变化获得设计上的控制，使得侧视角下同一像素区域内蓝像素子单元互补的亮度饱和趋势控制接近于红像素子单元及绿像素子单元。而在正视角下，由于相邻像素单元的互补调整，能够满足红、绿、蓝各像素子单元的亮度比例维持传统技术原有的比例。即，本申请实施例能同时使得正视角和侧视角下，同一像素区域内红、绿、蓝各像素子单元亮度饱和的趋势相近，从而改善侧视角的色偏情况。由于像素单元的尺寸非常小，包括若干像素单元的像素区域的尺寸也较小，人眼观察时难以分辨像素区域内单个像素点的亮度差异，而是感觉各显示区域的整体亮度，因此本申请实施例在改善侧视角的色偏情况的同时，能够保证整体显示亮度的均匀性。
需要说明的是，本申请实施例使同一像素区域内相邻的蓝像素子单元的蓝色光阻膜厚存在差异，通过同一像素区域内多个蓝像素子单元的配合来补偿视角色差，因此信号调整上需牺牲蓝像素子单元的解析度。例如，在同一帧的显示时间内对同一像素区域内位于同一行/列的多个蓝像素子单元施加相同的电压信号，以获得光阻膜厚差异补偿视角色差的效果。
通过对每个像素区域内的蓝像素子单元进行光学特性上的调整，使得无需对同一像素子单元再进行划分以施加不同的驱动电压，使得无需额外设计金属或TFT元件来驱动次像素，因此不需要牺牲可透光开口区、能够保持良好的面板透光率，节约背光成本。
在一个实施例中，每一所述像素区域内包括多个呈阵列排布的像素单元。 其中每一所述像素区域中像素单元的行数与列数相同或不同。优选的，每一所述像素区域中像素单元的行数与列数相同，即，每一所述像素区域中，像素单元的行数与像素单元的列数相同，并且第i行第j列的蓝色光阻膜层厚度与第j行第i列的蓝色光阻膜层厚度相同，其中i与j均小于或等于所述行数。
在一个实施例中，每一所述像素区域包括四个像素单元，所述四个像素单元呈两行及两列分布，即，所述四个像素单元排列为2×2矩阵。如图1所示，一像素区域包括四个像素单元，该四个像素单元分别为Pi，j、Pi，j+1、Pi+1， j及Pi+1，j+1，其对应的四个蓝像素子单元的蓝色光阻膜层分别为Bi，j、Bi，j+1、Bi+1，j及Bi+1，j+1。
作为一种实施方式，互为对角的两个像素单元中的蓝像素子单元具有相同厚度的蓝色光阻膜层，即蓝色光阻膜层Bi，j与蓝色光阻膜层Bi+1，j+1的厚度相同，记为B-CF21；蓝色光阻膜层Bi，j+1与蓝色光阻膜层Bi+1，j的厚度相同，记为B-CF22。其中，厚度B-CF21对应的gap值为B-Gap21，厚度B-CF22对应的gap值为B-Gap22。由于同一像素区域内存在两种gap值，使得该像素区域整体的相位延迟量约等于两种gap值对应的相位延迟量的均值，相当于调整了像素区域整体的光学参数产生互补的光学效果，使得侧视角下同一像素区域内蓝像素子单元互补的亮度饱和趋势控制接近于红像素子单元及绿像素子单元，从而改善侧视角的色偏情况。
此时，在同一帧的显示时间内对该像素区域内位于同一行/列的多个蓝像素子单元施加相同的电压信号，以获得光阻膜厚差异补偿视角色差的效果。例如，通过时序控制电路对各像素子单元的初始驱动电压进行处理，将该像素区域内位于同一行/列的多个蓝像素子单元的驱动电压转换为该行/列各蓝像素子单元的初始驱动电压均值，并在下一帧或间隔至少一帧的显示时间输出处理后的驱动电压信号。又如，在第N帧的显示时间，时序控制电路接收各像素子单元的初始驱动电压信号，其中像素Pi，j、像素Pi，j+1、像素Pi+1，j及像素Pi+1，j+1的蓝像素子单元的初始驱动电压分别为BNi，j、BNi，j+1、BNi+1， j和BNi+1，j+1，时序控制电路对初始驱动电压BNi，j、BNi，j+1、BNi+1，j和BNi+1， j+1进行处理。其中，一种处理方式是使实际施加到像素Pi，j和像素Pi，j+1的蓝像素子单元中的驱动电压为BNi，j与BNi，j+1的均值，使实际施加到像素Pi+1，j和像素Pi+1，j+1的蓝像素子单元中的驱动电压为BNi+1，j与BNi+1，j+1的均值。另一种处理方式是使实际施加到像素Pi，j和像素Pi+1，j的蓝像素子单元中的驱动电压为BNi，j与BNi+1，j的均值，使实际施加到像素Pi，j+1和像素Pi+1，j+1的蓝像素子单元中的驱动电压为BNi，j+1与BNi+1，j+1的均值。而处理后的驱动电压信号(即实际施加到各像素子单元上的驱动电压信号)将延后至少一帧的时间传送至显示面板。优选地，时序控制电路在第N帧的显示时间接收各像素子单元的初始驱动电压信号，在第N+1帧的显示时间将处理后的驱动电压信号输出至显示面板的各像素单元，即图像数据将延后一帧的时间传送至显示面板，图像的显示将延后一帧的时间。
此时，如图2所示，Target曲线为蓝像素子单元的亮度随电压增加的目标变化曲线，b sub-pixcel 2曲线为B-CF21对应的蓝像素子单元的亮度随电压增加的目标变化曲线，b sub-pixcel 1曲线为B-CF22对应的蓝像素子单元的亮度随电压增加的目标变化曲线，其中B-CF21＞B-CF22。Mix曲线为上述阵列基板中一显示区域内蓝像素子单元的整体出光亮度随电压增加的变化曲线，该阵列基板中任意相邻的两个蓝像素子单元的蓝色光阻膜层厚度分别B-CF21为和B-CF22。根据图2可知，相较于b sub-pixcel 1曲线和b sub-pixcel2曲线，Mix曲线更加接近目标变化曲线，即上述任意相邻的两个蓝像素子单元的蓝色光阻膜层厚度不同的阵列基板的出光亮度更加满足侧视角的色偏要求。
作为另一种实施方式，同一像素区域内的四个像素单元中的蓝像素子单元的蓝色光阻膜层的厚度各不一样，即同一像素区域内具有四种蓝色光阻膜层厚度。例如，图1中像素Pi，j、像素Pi，j+1、像素Pi+1，j和像素Pi+1，j+1的四个蓝像素子单元蓝色光阻膜层Bi，j、Bi，j+1、Bi+1，j和Bi+1，j+1的厚度均不相同。此时，可通过时序控制电路对各像素子单元的初始驱动电压进行处理，将该像素区域内各个蓝像素子单元的驱动电压转换为该四个蓝像素子单元的初始 驱动电压的均值，并在下一帧或间隔至少一帧显示时间输出处理后的驱动电压信号。
在一个实施例中，为了使侧视角下每一像素区域内蓝像素子单元的整体亮度随电压增加的变化曲线更接近目标变化曲线，使每一像素区域内所述蓝像素子单元的光阻膜层具有更多种厚度。这样，同一像素区域的蓝像素子单元的光阻膜层与TFT基板之间存在更多种gap值，能够更细致地调节蓝像素子单元的光学特性曲线，使显示面板的显示效果更佳。
作为一种实施方式，每一所述像素区域包括九个像素单元，所述九个像素单元呈三行及三列分布，即，所述四个像素单元排列为3×3矩阵。例如，一像素区域中的九个像素单元按照如下矩阵排布：

一实施例中，该三行三列的像素矩阵对应的各蓝像素子单元中的蓝色光阻膜层的膜厚矩阵为：
Figure PCTCN2017101369-appb-000004
即，像素Pi，j、像素Pi+1，j+1和像素Pi+2，j+2的蓝像素子单元中具有相同厚度的蓝色光阻膜层，像素Pi，j+1、像素Pi+1，j、像素Pi+1，j+2和像素Pi+2，j+1的蓝像素子单元中具有相同厚度的蓝色光阻膜层，像素Pi，j+2和像素Pi+2，j的蓝像素子单元中具有相同厚度的蓝色光阻膜层。在一较优实施例中，B-CF33＞B-CF32＞B-CF31。此时，同一像素区域内蓝像素子单元的光阻膜层与TFT基板之间存在三种gap值，由小到大分别记为B-Gap31、B-Gap32及B-Gap33，它们分别对应的相位延迟量分别记为ΔndB-Gap31、ΔndB-Gap32、ΔndB-Gap33及ΔndB-Gap34，由于B-Gap31、B-Gap32及B-Gap33的差异，使得同一像素区域 内蓝像素子单元实际的相位延迟量约等于ΔndB-Gap31、ΔndB-Gap32及ΔndB-Gap33的均值，能够产生互补的光学效果，补偿视角色差造成的影响，从而改善侧视角色偏的问题。
其中，为了获得较好的色偏改善效果，一种实施方式是，通过时序控制电路对各像素子单元的初始驱动电压信号进行处理，使处理后，像素Pi，j、像素Pi，j+1和像素Pi，j+2的驱动电压为它们的初始驱动电压的均值；像素Pi+1，j、像素Pi+1，j+1和像素Pi+1，j+2的驱动电压为它们的初始驱动电压的均值；像素Pi+2， j、像素Pi+2，j+1和像素Pi+2，j+2的驱动电压为它们的初始驱动电压的均值。另一种实施方式是，通过时序控制电路对各像素子单元的初始驱动电压信号进行处理，使处理后，像素Pi，j、像素Pi+1，j和像素Pi+2，j的驱动电压为它们的初始驱动电压的均值；像素Pi，j+1、像素Pi+1，j+1和像素Pi+2，j+1的驱动电压为它们的初始驱动电压的均值；像素Pi，j+2、像素Pi+1，j+2和像素Pi+2，j+2的驱动电压为它们的初始驱动电压的均值。
另一实施例中，同一像素区域内的九个像素单元中的蓝像素子单元的蓝色光阻膜层的厚度各不一样，即同一像素区域内具有九种蓝色光阻膜层厚度。此时，可通过时序控制电路对各像素子单元的初始驱动电压进行处理，将该像素区域内各个蓝像素子单元的驱动电压转换为该九个蓝像素子单元的初始驱动电压的均值，并在下一帧或间隔至少一帧显示时间输出处理后的驱动电压信号。
作为一种实施方式，每一所述像素区域包括十六个像素单元，所述十六个像素单元呈四行及四列分布，即，所述四个像素单元排列为4×4矩阵；例如，一像素区域中的十六个像素单元按照如下矩阵排布：
Figure PCTCN2017101369-appb-000005
一个实施例中，该四行四列的像素矩阵对应的各蓝像素子单元中的蓝色光阻膜层的膜厚矩阵为：
Figure PCTCN2017101369-appb-000006
即，像素Pi，j和像素Pi+3，j+3的蓝像素子单元中具有相同厚度的蓝色光阻膜层，像素Pi，j+1、像素Pi+1，j、像素Pi+1，j+2、像素Pi+2，j+1、像素Pi+2，j+3和像素Pi+3，j+2的蓝像素子单元中具有相同厚度的蓝色光阻膜层，像素Pi，j+2、像素Pi+1，j+1、像素Pi+1，j+3、像素Pi+2，j、像素Pi+2，j+2和像素Pi+3，j+1的蓝像素子单元中具有相同厚度的蓝色光阻膜层，像素Pi，j+3和像素Pi+3，j的蓝像素子单元中具有相同厚度的蓝色光阻膜层。在一较优实施例中，B-CF44＞B-CF43＞B-CF42＞B-CF41。如图3所示，此时每一像素区域内蓝像素子单元的光阻膜层与TFT基板之间存在四种gap值，由小到大分别记为B-Gap41、B-Gap42、B-Gap43及B-Gap44，它们分别对应的相位延迟量分别记为ΔndB-Gap41、ΔndB-Gap42、ΔndB-Gap43及ΔndB-Gap44，由于B-Gap41、B-Gap42、B-Gap43及B-Gap44的差异，使得蓝像素子单元实际的相位延迟量约等于ΔndB-Gap41、ΔndB-Gap42、ΔndB-Gap43及ΔndB-Gap44的均值，能够产生互补的光学效果，补偿视角色差造成的影响，从而改善侧视角色偏的问题。
其中，为了获得较好的色偏改善效果，一种实施方式是，通过时序控制电路对各像素子单元的初始驱动电压信号进行处理，使处理后，像素Pi，j、像素Pi，j+1、像素Pi，j+2和像素Pi，j+3的驱动电压为它们的初始驱动电压的均值；像素Pi+1，j、像素Pi+1，j+1、像素Pi+1，j+2和像素Pi+1，j+3的驱动电压为它们的初始驱动电压的均值；像素Pi+2，j、像素Pi+2，j+1、像素Pi+2，j+2和像素Pi+2，j+3的驱动电压为它们的初始驱动电压的均值；像素Pi+3，j、像素Pi+3，j+1、像素Pi+3， j+2和像素Pi+3，j+3的驱动电压为它们的初始驱动电压的均值。另一种实施方式是，通过时序控制电路对各像素子单元的初始驱动电压信号进行处理，使处 理后，像素Pi，j、像素Pi+1，j、像素Pi+2，j和像素Pi+3，j的驱动电压为它们的初始驱动电压的均值；像素Pi，j+1、像素Pi+1，j+1、像素Pi+2，j+1和像素Pi+3，j+1的驱动电压为它们的初始驱动电压的均值；像素Pi，j+2、像素Pi+1，j+2、像素Pi+2， j+2和像素Pi+3，j+2的驱动电压为它们的初始驱动电压的均值；像素Pi，j+3、像素Pi+1，j+3、像素Pi+2，j+3和像素Pi+3，j+3的驱动电压为它们的初始驱动电压的均值。
另一实施例中，同一像素区域内的十六个像素单元中的蓝像素子单元的蓝色光阻膜层的厚度各不一样，即同一像素区域内具有十六种蓝色光阻膜层厚度。此时，可通过时序控制电路对各像素子单元的初始驱动电压进行处理，将该像素区域内各个蓝像素子单元的驱动电压转换为该十六个蓝像素子单元的初始驱动电压的均值，并在下一帧或间隔至少一帧显示时间输出处理后的驱动电压信号。
在一个实施例中，在每一所述像素单元内，所述绿像素子单元位于所述红像素子单元和所述蓝像素子单元的中间。这样有利于红、绿、蓝三种原色混合得到各种颜色。
在一个实施例中，所述阵列基板还包括遮光层，所述遮光层形成在所述衬底上，并且具有开口，所述光阻膜层设置于所述遮光层的开口处。在某些实施例中，遮光层可以是黑矩阵，其中，具有开口的遮光层可以理解为包围各像素子单元的黑色边框。通过具有开口的遮光层将衬底划分为若干像素单元，并将每个像素单元划分为红、绿、蓝三个像素子单元。在遮光层的开口处填充制备相应颜色的光阻膜层，得到阵列基板。其中，遮光层能够防止背景光泄漏，提高显示对比度，还能防止混色以增加颜色的纯度。可选地，遮光层采用金属铬材料或黑色树脂材料制备得到，例如，所述遮光层的厚度大于光阻膜层的厚度。例如，所述遮光层包括规则矩阵排列的若干黑单元体，每一黑单元体具有所述开口；相邻两所述黑单元体相互连接，即，各黑单元体紧密排列。或者，遮光层为黑框架，其上开设若干开口，各所述开口排列为矩阵。黑框架采用金属铬材料或黑色树脂材料制备得到。
请参阅图4，其为又一实施例的阵列基板的结构示意图。该阵列基板40 包括衬底41，衬底41上设置有若干像素单元，每一像素单元包括第一像素子单元、第二像素子单元及第三像素子单元，其中衬底41的每一像素子单元上设置有光阻膜层42，并且同一像素单元内的不同像素子单元分别设置由不同材料制得的光阻膜层，以使同一像素单元内的不同像素子单元的发光颜色不同。例如，第一像素子单元为红像素子单元，第二像素子单元为绿像素子单元，第三像素子单元为蓝像素子单元，则第一像素子单元上设置有红色光阻膜层422R，第二像素子单元上设置有绿色光阻膜层422G，第三像素子单元上设置有蓝色光阻膜层422B。其中，光阻膜层位于衬底41与第二基板之间，并且，第三像素子单元的光阻膜层422B具有阶梯结构，即蓝色光阻膜层422B具有阶梯结构。
在本实施例中，阶梯结构使得第三像素子单元内的光阻膜层具有不同的膜厚，使得在第三像素子单元内，蓝色光阻膜层与第二基板之间存在不同的间隙距离，其中，光阻膜层与第二基板之间的间隙距离又称gap值。各像素子单元的光学特性参数与gap值相关，例如，各像素子单元的相位延迟量与gap值相关，而相位延迟量的大小会影响光偏振态的变化，进而影响像素子单元的出光亮度。也就是说，在相同电压下，各像素子单元的出光亮度与gap值相关，且不同的像素子单元的出光亮度与gap值之间，存在不同的曲线关系。
本实施例中，由于第三像素子单元存在多种gap值，使得侧视角下第三像素子单元的光学特性随电压变化的曲线等效为多种gap值对应的曲线的平均值，从而使得侧视角混光下，第三像素子单元的亮度变化获得设计上的控制，使得侧视角下第三像素子单元互补的亮度饱和趋势控制接近于第一像素子单元及第二像素子单元。而在正视角下，由于相邻像素单元的互补调整，能够满足红、绿、蓝各像素子单元的亮度比例维持传统技术原有的比例。即，本申请实施例能同时使得正视角和侧视角下，红、绿、蓝各像素子单元亮度饱和的趋势相近，从而改善侧视角的色偏情况。
通过对每个像素单元中的第三像素子单元进行光学特性上的调整，使得 无需对同一像素子单元再进行划分以施加不同的驱动电压，使得无需额外设计金属或TFT元件来驱动次像素，因此不需要牺牲可透光开口区、能够保持良好的面板透光率，节约背光成本。
在一个实施例中，每一像素单元内，第三像素子单元与第二像素子单元相邻设置，并且，阶梯结构的厚度在远离第二像素子单元的方向上减小。例如，阶梯结构的厚度在远离第二像素子单元的方向上逐渐减小。这样，在靠近第二像素子单元的位置，蓝色像素子单元的gap值较小，出光亮度较小，能够综合调整第三像素子单元整体的出光亮度，延缓侧视角下第三像素子单元整体的亮度饱和趋势，使其接近于第一像素子单元及第二像素子单元，从而改善侧视角的色偏情况。在远离第二像素子单元的位置，蓝色像素子单元的gap值较大，出光亮度较大，能够补偿人眼对蓝光的不敏感。
在一个实施例中，第一像素子单元、第二像素子单元及第三像素子单元分别与衬底具有相同的接触面积，并且第一像素子单元也与第二像素子单元相邻设置，即第二像素子单元位于第一像素子单元和第三像素子单元之间。这样，有利于红、绿、蓝三种原色混合得到各种颜色。
在一个实施例中，第三像素子单元的光阻膜层具有两层阶梯结构。这样，两层阶梯结构具有两种厚度，例如靠近第二像素子单元的阶梯为第一厚度，远离第二像素子单元的阶梯为第二厚度。在一较佳实施例中，第一厚度大于第二像素子单元的光阻膜层的厚度，第二厚度小于第二像素子单元的光阻膜层的厚度。此时，具有两层阶梯结构的第三像素子单元的出光亮度更加满足侧视角的色偏要求。
在一个实施例中，为了使侧视角下第三像素子单元的整体亮度随电压增加的变化曲线更接近目标变化曲线，使第三像素子单元的光阻膜层具有更多层阶梯结构。例如，使第三像素子单元的光阻膜层具有至少三层阶梯结构。这样，第三像素子单元的光阻膜层与第二基板之间存在更多种gap值，能够更细致地调节第三像素子单元的光学特性曲线，使显示面板的显示效果更佳。又如，使第三像素子单元的光阻膜层具有四层阶梯结构，此时第三像素子单 元的光阻膜层与第二基板之间存在四种gap值，由小到大分别记为B-Gap1、B-Gap2、B-Gap3及B-Gap4，它们分别对应的相位延迟量分别记为ΔndB-Gap1、ΔndB-Gap2、ΔndB-Gap3及ΔndB-Gap4，由于B-Gap1、B-Gap2、B-Gap3及B-Gap4的差异，使得第三像素子单元实际的相位延迟量约等于ΔndB-Gap1、ΔndB-Gap2、ΔndB-Gap3及ΔndB-Gap4的均值，能够产生互补的光学效果，补偿视角色差造成的影响。
其中，作为一种实施方式，如图5a所示，在远离第二像素子单元的方向上，至少三层阶梯结构的厚度均匀减小，这样，能够简化第三像素子单元内的光阻膜层的制备工艺。作为另一种实施方式，如图5b所示，在远离第二像素子单元的方向上，至少三层阶梯结构的厚度呈曲线趋势减小，这样，蓝色像素子单元在远离绿色像素子单元的方向上的亮度的增加趋势更加平缓，使得蓝色像素子单元发出的蓝光与红色像素子单元发出的红光、绿色像素子单元发出的绿光的混合更加均匀，显示面板整体的混色效果更佳。
