 本发明的最佳实施方式
为让本发明上述目的、特征及优点更明显易懂，下文特举本发明较佳实施例，并配合附图，作详细说明如下。再者，本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
请参考图2和图3所示，图2是本发明一实施例的液晶显示器的像素结构示意图；图3是沿图2的AA割面线所绘示的本发明第一实施例的液晶显示器的局部剖面示意图。所述液晶显示器可为一薄膜晶体管液晶显示器，但不在此限，如图3所示，其基本包含两相对设置的第一基板10、第二基板11与设置于基板之间的液晶层12。所述液晶显示器具有一像素阵列，如图2所示，所述像素阵列包含多个子像素单元100排成阵列形式。一般而言，每一所述子像素单元100对应一薄膜晶体管单元，通过控制薄膜晶体管单元的开关，可以控制对应的子像素单元100显示其所对应的色光。在一实施例中，三个相邻的子像素单元100分别发出不同色光，例如红、绿、蓝，进而组成一像素单元。
如图3所示，为了让所述子像素单元100能够显示特定色光，所述液晶显示器还包含有一彩色滤光片2，设置在其中一基板上，例如第二基板11。所述彩色滤光片2是由不同颜色的光刻胶所形成，其主要包含复数滤光单元20以及一黑色矩阵层21。
所述滤光单元20间隔排列成一阵列，其中每一滤光单元20位置对应所述液晶显示装置的子像素单元100。在一实施例中，所述滤光单元20基本可包含红色滤光单元、蓝色滤光单元、绿色滤光单元。在一优选实施例中，所述红色滤光单元、蓝色滤光单元、绿色滤光单元在行方向上交替排列。故所述滤光单元20可视为排列成多行。通过开启子像素单元100，可使得所述液晶显示装置的背光源发出的光穿过所述子像素单元100所对应的滤光单元20，进而形成特定的色光。
如图3所示，所述黑色矩阵层21形成于所述滤光单元20之间，其中位于相邻两所述滤光单元20之间的黑色矩阵层21在横截面上包含一宽度较宽的上部210A与一宽度较窄的下部210B。更详细而言，在每一行的滤光单元20中，位于相邻两所述滤光单元20之间的黑色矩阵层21在横截面上包含所述上部210A与所述下部210B。
在图3实施例中，所述黑色矩阵层21在横截面上的上部210A呈一较长的长方形；所述下部210B呈一较短的长方形。
在图3中，假想线L1表示为现有液晶显示器会发生色偏现象的临界线；假想线L2则表示为本发明的液晶显示器会发生色偏现象的临界线，从图3的假想线L1和L2的比较可看出，所述黑色矩阵层21突出的下部210B有助于在大视角下阻挡来自其他相邻像素区的光线，进而限缩会发生色偏现象的视角范围。换言之，液晶显示器不会发生色偏现象的视角范围因此扩大，进而提高了画面的显示品质。
上述的黑色矩阵层21可以通过多灰阶光罩(Gray Tone或Half Tone)经过一次曝光、显影后实现，不需要增加额外的工序。
除了上述实施例之外，所述黑色矩阵层21在横截面上具有不同宽度的上部与下部的具体态样亦可由下列不同实施例实现。
参考图4所示，图4是沿图2的AA割面线所绘示的本发明第二实施例的液晶显示器的局部剖面示意图。在本实施例中，所述黑色矩阵层在横截面上的上部210A呈一较长的长方形；所述下部210B呈一梯形；其中所述梯形的上底与所述上部210A相连；所述梯形的上底长度大于所述梯形的下底长度。
参考图5所示，图5是沿图2的AA割面线所绘示的本发明第三实施例的液晶显示器的局部剖面示意图。在本实施例中，所述黑色矩阵层在横截面上的下部210B两侧具有弧状凹部211。
参考图6所示，图6是沿图2的AA割面线所绘示的本发明第四实施例的液晶显示器的局部剖面示意图。在本实施例中，所述黑色矩阵层在横截面上的上部210A与下部210B整体呈一梯形。
参考图7所示，图7是沿图2的AA割面线所绘示的本发明第五实施例的液晶显示器的局部剖面示意图。在本实施例中，在本发明的一实施例中，所述黑色矩阵层在横截面上的上部210A两侧具有弧状凹部212；所述下部210B呈一长方形。
综上所述，本发明主要是在相邻的滤光单元之间形成一黑色矩阵层，其在横截面上具有不同宽度的上部与下部，相较于现有的彩色滤光片，所述突出的下部有助于在大视角下阻挡来自其他相邻像素区的光线，进而改善在大视角下的色偏现象，提高液晶显示器画面显示品质。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
