该 2D显示面板与光栅之间还设置有第一支撑层， 该第一支撑层包括多 条高度相等的第一支撑体， 其中， 第一支撑体沿着该 2D 显示面板中的黑矩 阵条纹的方向覆盖黑矩阵条纹。
本发明实施例中所涉及的 "相等" 的含义是指完全相等或差值在规范允 许的范围内； "多个" 的含义是表示两个或两个以上。
本发明实施例提供的显示装置中， 由于在 2D 显示面板与光 »之间设置 了包括多条高度相等的第一支撑体的第一支撑层， 使光栅和 2D 显示面板之 间的间距保持均一， 并旦， 由于第一支撑体覆盖该 2D 显示面板中的黑矩阵 条紋， 从而降低了莫尔条紋。
需要说明的是， 莫尔条紋是由 2D显示面板中 BM (主要是 BM中的竖直 方向的条紋：）与光栅发生干涉现象而形成的， 由于本发明实施例中第一支撑 体沿着该 2D显示面板中的 BM条纹的方向覆盖 BM条纹， 即多个第一支撑 体将 BM中竖直方向的条紋变得杂乱， 从而降低了莫尔条紋的产生。
下面列举两个具体实施例， 对本发明实施例提供的显示装置进行说明。 实施例一、 本实施例中显示装置包括第一支撑层和第二支撑层。
本实施例提供的显示装置的结构参见图 2所示， 从下到上依次包括： 偏 光片 21、 2D显示面板 22、 偏光片 23、 第一支撑层 24、 间隔基板 25、 第二 支撑层 26、 主动式光栅 27、 以及主动式光栅偏光片 28;
其中， 第一支撑层 24包括多条高度相等的第一支撑体 241， 其中， 第一 支撑体 241沿着该 2D显示面板 22中的 BM条紋（图中未示）的方向覆盖 BM 条紋；第二支撑层 26包括位于 BM外围区域内— 高度相等的至少一个第二支 撑体 261。
本实施例中，第一支撑层 24中除第一支撑体 241之外的区域内填充有粘 接胶 242， 在制作时， 由于第一支撑体与粘接胶的固化收缩率不同， 因此， 根据第一支撑体与粘接胶的固化收缩率设定第一支撑体与粘接胶的高度， 以 使其固化后的高度相同， 提高第一支撑层的平整度。
本实施例中，第二支撑层 26中除第二支撑体 261之外的区域内填充有粘 接胶 262， 在制作时， 由于第二支撑体与粘接胶的固化收缩率不同， 因此， 根据第二支撑体与粘接胶的固化收缩率设定第二支撑体与粘接胶的高度， 以 使其固化后的高度相同， 提高第二支撑层的平整度。
本实施例中， 优选的， 至少一个第二支撑体 261组合成闭合图形。 此, 能够进一步提高第二支撑层的平整度。
本实施例中， 优选的， 第一支撑体和第二支撑体采 )¾相同的 ^料制作。 当然， 第一支撑体与第二支撑体也可以采 ^不同的材料制作， 如第一支撑体 采用透明材料， 而第二支撑体采 ffi不透明材料。
本实施例中， 第一支撑体采用折射率较大（如折射率大于 1.5 ) ϋ硬度较 大 （如大于 〗Η铅笔硬度） 的透明绝缘材料制作， 如感光高分子化合物 （如 dam胶等）、 硅球等， 又如含硫、 溴、 碘、 磷、 和 /或砜基等高折射率基团的 透明且可光固化或热固化的树脂。
本实施例中，第一支撑层 24所包含的多条高度相等的第一支撑体 241的 俯视结构参见图 3所示， 多条第一支撑体 241等间距且平行排列， 第一支撑 体长度方向的形状为折线形或曲线形 （图 3 以折线形为例）。 该第一支撑层 24的剖面结构如图 4所示。 通过将第一支撑体长度方向的形状设置成折线形 或曲线形， 降低了光线的干涉， 以达到降低莫尔纹的目的。
在实施中， 优选的， 第一支撑体的最大宽度的中心线与其覆盖的 BM条 纹的中心线重合。 第一支撑层与 BM对位后的结构参见图 5所示， 其中， 第 一支撑体 24i的最大宽度的中心线与其覆盖的 BM条紋的中心线重合， 参见 图 6所示。 BM条紋与该条紋上覆盖的第一支撑体叠加后所形成的图形如图 7 所示， 改变了光线的传输路径， 降低了光线的干涉， 以达到降低莫尔紋的目 的。
本实施例中， 第一支撑层位于 2D显示面板与间隔基板之间， 与 2D显示 面板的距离较近， 并且第一支撑层位于 2D显示面板的 BM上， 因此， 该第 一支撑层不会对 2D 显示面板中的显示子像素的光线传播产生影响。 并—巨.， 本实施例中， 第二支撑层位于光 *与间隔基板之间， 与 2D 显示面板的距离 较远 （一般间隔基板的厚度为 1 - l Omm ) , 若第二支撑层与第一支撑层采用相 同的结构， 则会影响光线进入光栅的传播方向， 即光线通过第二支撑层后会 发生折射， 从而增加了 3D 串扰， 因此， 采用本实施例的第二支撑层， 不会 增加 3D串扰。
实施例二、本实施例中显示装置包括第一支撑层， 但不包括第二支撑层。 本实施例提供的显示装置的结构参见图 8所示， 从下到上依次包括： 偏 光片 81、 2D显示面板 82、 偏光片 83、 第一支撑层 84、 间隔基板 85、 以及 透镜光極 86： 其中， 第一支撑层 84包括多条高度相等的第一支撑体 841， 其中， 第一 支撑体 84】沿着该 2D显示面板 82中的 BM条紋（图中未示）的方向覆盖 BM 条紋。
本实施例中，第一支撑层 84中除第一支撑体 841之外的区域内填充有粘 接胶 842， 在制作时， 由于第一支撑体与粘接胶的固化收缩率不同， 因此， 根据第一支撑体与粘接胶的固化收缩率设定第一支撑体与粘接胶的高度， 以 使其固化后的高度相同， 提高第一支撑层的平整度。
本实施例中， 优选的， 第一支撑体采用透明 料。
本实施例中， 第一支撑体采用折射率较大（如折射率大于 1.5 ) ϋ硬度较 大的透明绝缘材料制作， 如感光高分子化合物 （如 dam胶等）、 硅球等。
本实施例中， 第一支撑体 84】 长度方向的形状为折线形或曲线形， 具体 参见实施例一的描述。 由此， 降低了光线的干涉， 以达到降低莫尔纹的目的。
在实施中， 优选的， 第一支撑体的最大宽度的中心线与其覆盖的 BM条 紋的中心线重合， 具体参见实施例一的描述。 由于改变了光线的传输路径， 从而降低了光线的干涉， 以达到降低莫尔纹的目的。
本实施例中， 第一支撑层位于 2D显示面板与间隔基板之间， 与 2D显示 面板的距离较近， 并且第一支撑层位于 2D显示面板的 BM上， 因此， 该第 一支撑层不会对 2D显示面板中的显示子像素的光线传播产生影响。
本发明实施例提供的显示装置可以为： 液晶显示面板、 电子纸、 有机发 光二极管 (Organic Light Emitting Diode, OLED) 面板、 手机、 平板电脑、 电视机、 显示器、 笔记本电脑、 数码相框、 导航仪等任何具有显示功能的产 品或部件。
尽管已描述了本发明的优选实施例， 但本领域内的技术人员一旦得知了 基本创造性概念， 则可对这些实施例作出另外的变更和修改。 所以， 所附权 利要求意欲解释为包括优选实施例以及落入本发明范围的所有变更和修改。
显然， 本领域的技术人员可以对本发明进行各种改动和变形而不脱离本 发明的精神和范围。 这样， 倘若本发明的这些修改和变形属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变形在内。
