本发明实施例提供的液晶显示器包括限位结构， 还包括 TFT基板、 贴附 于 TFT基板的内侧面的 CF基板和设于 TFT基板的内侧面上特定区域以外的 部分或全部区域的胶粘层。 TFT基板通过胶粘层固定到限位结构上。 其中， CF基板的内侧面贴附于 TFT基板的内侧面上。 TFT基板内侧面上的特定区 域包括 TFT基板内侧面与 CF基板内侧面的重合区域以及 TFT基板的内侧面 上用于连接柔性电路板的区域。
需要说明的是，所述 TFT基板的内侧面指的是其与 CF基板相对的一面， 同理， 所述 CF基板的内侧面指的是其与 TFT基板相对的一面， 即 TFT基板 和 CF基板的内侧面相对。 其中， 在 TFT基板和 CF基板的内侧面上均包含 显示区域和非显示区域，在 TFT基板的显示区域设置有用于控制不同像素的 TFT阵列， 在 CF基板的显示区域设置有对应不同像素的色阻， 所述将 CF 基板贴附于 TFT基板的内侧面上指的是，将 TFT基板的内侧面与 CF基板的 内侧面正对区域边缘位置的非显示区域上涂布封框胶将 TFT基板和 CF基板 牢固粘接， 在 TFT基板和 CF基板之间的封闭空间内注入液晶形成液晶盒。

TFT基板 102的内侧面的四条边均大于 CF基板 103的内侧面对应的四 条边， 即 TFT基板 102的内侧面的 X侧边的边长大于 CF基板 103的内侧面 对应的 X侧边的边长， TFT基板 102的内侧面的 Y侧边的边长大于 CF基板 103的内侧面对应的 Y侧边的边长， TFT基板 102的内侧面的 Z侧边的边长 大于 CF基板 103的内侧面对应的 Z侧边的边长， TFT基板 102的内侧面的 T侧边的边长大于 CF基板 103的内侧面对应的 T侧边的边长。
实施例中， 由于 TFT基板 102的内侧面的四条边大于 CF基板 103的内 侧面对应的四条边， 从而扩大了胶粘层 104的位置， 实现保证无边框的液晶 显示器的稳定性。
例如，胶粘层 104设于 TFT基板 102的内侧面上特定区域以外的部分或 全部区域， 下面将分别进行介绍。
在具体实施例中，胶粘层 104设于 TFT基板 102的内侧面上特定区域以 外的部分区域。
比如， 在图 2A中， A区域为 TFT基板 102内侧面与 CF基板 103内侧 面的重合区域，一部分柔性电路板连接区域 105设于 TFT基板 102内侧面上 TFT基板 102的 X侧边与 CF基板 103的 X侧边之间的部分区域， 另一部分 柔性电路板连接区域 105设于 TFT基板 102内侧面上 TFT基板 102的 Y侧 边与 CF基板 103的 Y侧边之间的部分区域； 胶粘层 104设于 TFT基板 102 的内侧面上特定区域以外的部分区域。
在具体实施例中，胶粘层 104设于 TFT基板 102的内侧面上特定区域以 外的全部区域。
比如， 在图 2B中， A区域为 TFT基板 102内侧面与 CF基板 103内侧 面的重合区域，一部分柔性电路板连接区域 105设于 TFT基板 102内侧面上 TFT基板 102的 X侧边与 CF基板 103的 X侧边之间的部分区域， 另一部分 柔性电路板连接区域 105设于 TFT基板 102内侧面上 TFT基板 102的 Y侧 边与 CF基板 103的 Y侧边之间的部分区域； 胶粘层 104设于 TFT基板 102 的内侧面上特定区域以外的全部区域。
实施例中，由于胶粘层 104设于 TFT基板 102的内侧面上特定区域以外 的全部区域， 从而实现保证无边框的液晶显示器的稳定性。
在具体实施例中，在 TFT基板 102和 CF基板 103之间还封装有液晶层， TFT基板 102、 CF基板 103和液晶层构成液晶盒。
例如， 如图 1所示， 本发明实施例的液晶显示器还包括第一偏光片 106 和第二偏光片 107; 第一偏光片设于 TFT基板 102的外侧面上， 第二偏光片 107设于 CF基板 103的外侧面上。 其中， TFT基板 102的外侧面为与 TFT基板 102的内侧面相对的另一面； CF基板 103的外侧面为与 CF基板 103的内侧面相对的 CF基板 103的另一 面。
例如， 第一偏光片 106为垂直偏光片， 第二偏光片 107为水平偏光片， 或者第一偏光片 106为水平偏光片， 第二偏光片 107为垂直偏光片。
在实施例中， 由于液晶显示器包括第一偏光片 106和第二偏光片 107, 通过电压控制液晶偏转， 以及第一偏光片 106和第二偏光片 107的配合， 控 制光线透过率， 从而保证无边框的液晶显示器实现正常显示。
例如， 如图 3所示， 本发明实施例的液晶显示器还包括第一相位延迟膜 108和第二相位延迟膜 109;第一相位延迟膜 108设于第一偏光片 106和 TFT 基板 102之间， 第二相位延迟膜 109设于第二偏光片 107和 CF基板 103之 间。
其中， 第一相位延迟膜 108和第二相位延迟膜 109的相位延迟相反。 在具体实施例中， 任何能实现相反的相位延迟的第一相位延迟膜 108和 第二相位延迟膜 109都适用于本发明实施例。
_ λ λ 例如，第一相位延迟膜 108为 4相位延迟膜，第二相位延迟膜 109为 4

需要说明的是， 图 3为本发明实施例无边框液晶显示器俯视图的局部视 图。
实施例中， 由于液晶显示器包括第一相位延迟膜 108和第二相位延迟膜 109, 从而保证无边框的液晶显示器能够防止入射的环境光反射。
下面将以第一偏光片 106为垂直偏光片，第二偏光片 107为水平偏光片，
_ λ λ
第一相位延迟膜 108为 4相位延迟膜， 第二相位延迟膜 109为 4相位延迟 膜为例， 对本发明实施例的带有相位延迟膜的液晶显示器的显示原理进行说 明， 其他情况的实施方式与本发明实施例的实施方式类似， 在此不再赘述。 如图 4所示， 第一入射光通过第二偏光片 107成为水平偏振光， 该水平 偏振光通过第二相位延迟膜 109后成为左圓偏振光， 该左圓偏振光通过液晶 合
。
如果将液晶盒通电， 则左圓偏振光通过液晶盒后仍有左圓偏振光分量， 该左圓偏振光分量通过第一相位延迟膜 108后成为垂直偏振光， 该垂直偏振 光能够通过第一偏光片 106, 因而画面能够正常显示。
如果未将液晶盒通电， 则左圓偏振光通过液晶盒后成为右圓偏振光， 该 右圓偏振光通过第一相位延迟膜 108后成为水平偏振光， 该水平偏振光不能 通过第一偏光片 106, 因而画面无法显示。
其中， 第一入射光为背光源产生的光。
下面将以第一偏光片 106为垂直偏光片，第二偏光片 107为水平偏光片，
_ λ λ
第一相位延迟膜 108为 4相位延迟膜， 第二相位延迟膜 109为 4相位延迟 膜为例， 对本发明实施例的带有相位延迟膜的液晶显示器的防止入射的环境 光反射原理进行说明，其他情况的实施方式与本发明实施例的实施方式类似， 在此不再赘述。
如图 5所示， 第二入射光通过第一偏光片 106后成为垂直偏振光， 该垂 直偏振光通过第一相位延迟膜 108后成为左圓偏振光， 该左圓偏振光经过 TFT基板 102上的结构如电极反射后成为右圓偏振光， 该右圓偏振光通过第 一相位延迟膜 108后成为水平偏振光， 该水平偏振光不能通过垂直偏光片， 因而本发明实施例的带有相位延迟膜的液晶显示器能够防止入射的环境光反 射。
其中， 第二入射光为环境光。
例如， 本发明实施例的液晶显示器的 TFT基板上设有黑色遮光层， 用于 防止入射的环境光反射。黑色遮光层设置于 TFT基板内侧面上的显示区域各 个像素的周边区域和非显示区域上。
例如， 黑色遮光层为黑色树脂层。
下面将以第一偏光片 106为垂直偏光片， 第二偏光片 107为水平偏光片 为例，对本发明实施例的液晶显示器的 TFT基板 102包括黑色遮光层时的显 示原理进行说明， 其他情况的实施方式与本发明实施例的实施方式类似， 在 此不再赘述。
如图 6所示， 第一入射光通过第二偏光片 107后成为水平偏振光， 该水 平偏振光通过液晶盒。
如果将液晶盒通电， 则该水平偏振光通过液晶盒后成为垂直偏振光， 该 垂直偏振光能够通过第一偏光片 106, 因而画面能够正常显示。
如果未将液晶盒通电， 则该水平偏振光通过液晶盒后仍为水平偏振光， 该水平偏振光不能通过第一偏光片 106, 因而画面无法显示。
其中， 第一入射光为背光源产生的光。
下面将以第一偏光片 106为垂直偏光片， 第二偏光片 107为水平偏光片 为例，对本发明实施例的液晶显示器的 TFT基板 102包括黑色遮光层时的防 止入射的环境光反射原理进行说明， 其他情况的实施方式与本发明实施例的 实施方式类似， 在此不再赘述。
如图 7所示， 第二入射光通过第一偏光片 106后成为垂直偏振光， 该垂 直偏振光射入到 TFT基板 102, 由于 TFT基板 102包括黑色遮光层 110, 可 以吸收大部分光线， 使得第二入射光反射后得到的光很微弱， 从而本发明实 施例的 TFT基板 102包括黑色遮光层 110的液晶显示器能够防止入射的环境 光反射。
其中， 第二入射光为环境光。
例如， 如图 1、 图 3所示， 胶框 101设于 TFT基板 102内侧面上与 CF 基板 103内侧面的重合区域以外的区域以及第二偏光片 107上的周边区域， 用于支撑所述 TFT基板 102以及将所述 CF基板 103及位于其上的如第二偏 光片 107等结构固定在所述 TFT基板 102和胶框 101之间。
其中， TFT基板 102内侧面上与 CF基板 103内侧面的重合区域以外的 区域为 TFT基板 102内侧面上与 CF基板 103内侧面正对区域以外的区域。
其中， 胶框 101可以设于第二偏光片 107上的周边区域中的部分区域或 全部区域， 如设于第二偏光片 107周边区域的两个侧边、 三个侧边、 四个侧 边或者四个角等， 这些本发明均不做限定， 只要胶框可以将 CF基板稳固的 支撑， 使其与 TFT基板紧密结合即可。
比如， 假设无边框液晶显示器主视图如图 2A所示， 无边框液晶显示器 B部分的俯视图如图 1所示， 则如图 1所示， 一部分胶框 101设于 TFT基板 102内侧面上 TFT基板 102的 X侧边与 CF基板 103的 X侧边之间的区域， 一部分胶框 101设于 TFT基板 102内侧面上 TFT基板 102的 Y侧边与 CF 基板 103的 Y侧边之间的区域（被 CF基板 103和第二偏光片 107遮挡住的 部分在图 1中用虚线表示） ， 其余部分胶框 101设于第二偏光片 107上的周 边区域。
实施例中， 由于胶框 101设于 TFT基板 102内侧面与 CF基板 103内侧 面的重合区域以外的区域和第二偏光片 107上的周边区域， 从而保证无边框 的液晶显示器更稳定。
在具体实施例中，本发明实施例的液晶显示器还包括光源 LED11 Light Emitting Diode, 发光二极管） 、 光学膜层 112和背板 113 , 其中， 本发明实 施例的液晶显示器中 LED111、 光学膜层 112和背板 113相互之间的连接关 系与现有技术中 LED、 光学膜层和背板相互之间的连接关系相同。 其中， 图 中以侧入式光源为例进行示意， 光学膜层可以包括导光板、扩散膜、棱镜膜、 反射片等结构， 光源和反射片位于背板 113上， 反射片上为导光板和其他光 学膜片， 光源位于光学膜片中导光板的一侧； 对于直下式光源， 光学膜层可 以包括扩散板、 扩散膜、 棱镜膜、 反射片等结构， 光源置于背板 113上， 光 学膜层置于光源上方。连接在 TFT基板上的柔性电路板通过柔性扁平电缆从 光源的背面绕过， 置于背板之上， 进一步实现液晶显示器的无边框设计。
