所述彩膜基板又称CF基板（Color Filter Substrate）或彩色滤光片基板，参阅图1，彩膜基板10作为液晶显示面板的其中一块基板，与阵列基板（Thin Film Transistor Substrate，又称TFT基板、薄膜晶体管基板或Array基板）20相对间隔设置，两基板之间填充有液晶30。
下面结合本发明实施例中的附图，对本发明所提供的各个示例性的实施例的技术方案进行清楚、完整地描述。在不冲突的情况下，下述的实施例及实施例中的技术特征可以相互组合。
请参阅图2，为本发明一实施例的彩膜基板。所述彩膜基板10包括基体11以及依次层叠设置于基体11上的透光图案12、黑矩阵图案13和色阻图案14。其中，基体11可以为玻璃基体、塑料基体、可挠式基体等其他透光基体。透光图案12覆盖于基体11上，且透光图案12形成有凹槽结构121，该凹槽结构121的底部暴露对应区域的基体11的表面。所述透光图案12包括但不限于由透明光阻层进行图案化制程得到。黑矩阵图案13间隔形成于透光图案12上，并填充于透光图案12的凹槽结构121中，从而与凹槽结构121所暴露的基体11的表面接触。色阻图案14形成于透光图案12上，并填充于凹槽结构121中，从而与凹槽结构121所暴露的基体11的表面接触。
在本实施例中，色阻图案14包括多个颜色的色阻图案，例如图2所示的两两相邻的红色色阻图案R、绿色色阻图案G和蓝色色阻图案B，间隔设置的黑矩阵图案13与各个颜色色阻图案交错设置，即每一黑矩阵图案13形成于相邻两个色阻图案之间，用于防止漏光。
当然，在本发明的其他实施例中，色阻图案14也可以包括两两相邻的红色色阻图案R、绿色色阻图案G、蓝色色阻图案B和白色色阻图案，同样地，每一黑矩阵图案13形成于相邻两个色阻图案之间，用于防止漏光。
与现有技术的不同之处在于，本实施例在基体11和色阻图案14之间增加了一层具有凹槽结构121的透光图案12，通过凹槽结构121能够增大色阻图案14与透光图案12的接触面积，而透光图案12又与基体11相接触，相当于增大了色阻图案14与基体11的接触面积，从而能够尽量避免色阻图案14剥离，改善产品品质。
另外，本实施例还可以视为在基体11和黑矩阵图案13之间增加了一层具有凹槽结构121的透光图案12，通过凹槽结构121能够增大黑矩阵图案13与透光图案12的接触面积，而透光图案12又与基体11相接触，相当于增大了黑矩阵图案13与基体11的接触面积，从而能够尽量避免黑矩阵图案13剥离，避免漏光。
请继续参阅图2并结合图1，所述彩膜基板10还包括透明导电层15和间隔柱16。透明导电层15覆盖于色阻图案14上，可以为液晶显示面板的公共电极。间隔柱16形成于透明导电层15上，用于保持彩膜基板10和阵列基板20之间的距离，即限定液晶盒的厚度。需要说明的是，本发明实施例的前述发明目的也可以适用于不设置间隔柱16和/或透明导电层15的液晶显示面板。进一步地，本发明实施例也可以适用于不设置黑矩阵图案13的彩膜基板10，此时图1所示的黑矩阵图案13设置于阵列基板20一侧。
请参阅图3，为本发明一实施例的彩膜基板的制造方法。所述制造方法可以包括以下步骤S31~S33。
S31：提供一基体。
S32：在基体上形成覆盖基体的透光图案，且透光图案形成有凹槽结构，凹槽结构的底部暴露对应区域的基体。
S33：在透光图案上形成色阻图案，色阻图案填充于凹槽结构中。
结合图4所示，本实施例可以利用光罩对形成于基体41上的透明光阻层进行曝光等图案化制程以得到具有凹槽结构421的透光图案42。当然，根据透光图案42的制造材质不同，本发明实施例可利用其他图案化制程方式制得具有凹槽结构421的透光图案42。
本实施例可以利用光罩对形成于透光图案42上的色阻进行曝光、显影、刻蚀等图案化制程以得到具有预定图案的色阻图案43。其中，鉴于色阻图案43包括多个颜色的色阻图案，本发明实施例可以对同一颜色的色阻图案采用一次图案化制程，也可以通过一次图案化制程制得多个颜色的色阻图案。
采用本实施例方法制得的彩膜基板，通过凹槽结构421能够增大色阻图案43与透光图案42的接触面积，而透光图案42又与基体41相接触，相当于增大了色阻图案43与基体41的接触面积，从而能够尽量避免色阻图案43剥离，改善产品品质。
请参阅图5，为本发明另一实施例的彩膜基板的制造方法。所述制造方法可以包括以下步骤S51~S54。
S51：提供一基体。
S52：在基体上形成覆盖基体的透光图案，且透光图案形成有凹槽结构，凹槽结构的底部暴露对应区域的基体。
S53：在透光图案上形成间隔设置的黑矩阵图案，且黑矩阵图案填充于凹槽结构中，色阻图案覆盖黑矩阵图案。
S54：在透光图案上形成色阻图案，色阻图案填充于凹槽结构中。
请参阅图6，在前述实施例的描述基础上，本实施例可以利用光罩对形成于透光图案62上的黑矩阵层进行曝光、显影、刻蚀等图案化制程以得到具有预定图案的黑矩阵图案63。其中，黑矩阵图案63间隔形成于透光图案62上，并填充于透光图案62的凹槽结构621中，从而与凹槽结构621所暴露的基体61的表面接触。在本实施例中，色阻图64也形成于透光图案62上，并填充于凹槽结构621中，从而与凹槽结构621所暴露的基体61的表面接触。间隔设置的黑矩阵图案63与各个颜色色阻图案64交错设置，即每一黑矩阵图案63形成于相邻两个色阻图案64之间，用于防止漏光。
采用本实施例方法制得的彩膜基板，通过凹槽结构621能够增大黑矩阵图案63与透光图案62的接触面积，而透光图案62又与基体61相接触，相当于增大了黑矩阵图案63与基体61的接触面积，从而能够尽量避免黑矩阵图案63剥离，避免漏光。
请继续参阅图6，本发明实施例的制造方法还可以包括：在色阻图案64上形成覆盖于色阻图案64的透明导电层65；以及在透明导电层65上形成间隔柱66。其中，透明导电层65可以为液晶显示面板的公共电极。间隔柱66用于保持图1所示彩膜基板10和阵列基板20之间的距离，即限定液晶盒的厚度。需要说明的是，本发明实施例也可以适用于制造不设置间隔柱66和/或透明导电层65的彩膜基板。
综上所述，图3~图6所述实施例用于形成具有图2所示实施例的彩膜基板10，各个结构元件的材质以及所要形成的形状可参阅前述，因此具有与前述彩膜基板10相同的有益效果。
需要说明的是，以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用前述说明书及附图内容所作的等效结构或等效流程变换，例如各实施例之间技术特征的相互结合，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
