具体实施方式
为使本公开的实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，现有集成触控功能的显示装置包括依次层叠的显示面板07、触控面板08和偏光模组09，显示面板07和触控面板08之间通过贴合胶层01结合在一起，偏光模组09和触控面板08之间通过贴合胶层01结合在一起；或者，如图2所示，集成触控功能的显示装置包括依次层叠的显示面板07、触控面板08和偏光模组09，显示面板07和触控面板08整合在一起，偏光模组09和触控面板08之间通过贴合胶层01结合在一起。如图3所示，偏光模组09包括依次层叠的基底04、相位延迟层02和线性偏光层03，其中，基底04的材料可以为亚克力、三醋酸纤维薄膜TAC或光学材料COP；线性偏光层03形成在基底04上，相位延迟层02和线性偏光层03之间通过贴合胶层01结合在一起，在相位延迟层02上设置有用于与触控面板贴合的贴合胶层01。
可以看出，偏光模组09都是作为单独部件通过贴合胶层01与触控面板贴合整合，偏光模组09的基底以及贴合胶层01由于制程原因无法去除，偏光模组09的基底以及贴合胶层01等的存在增加了显示装置的厚度，不利于 柔性超薄的实现。
本公开实施例提供一种显示装置及其制作方法，能够降低显示装置的厚度。
本公开的实施例提供一种显示装置，包括：
显示面板；
位于显示面板出光侧的偏光模组，所述偏光模组包括沿远离所述显示面板的方向依次设置的相位延迟层和线性偏光层；
所述偏光模组的基底复用所述显示面板，或，复用位于所述显示面板和所述偏光模组之间的触控面板。
本实施例中，偏光模组直接制作在显示面板或触控面板上，这样能够省去偏光模组与显示面板或触控面板之间的贴合胶层以及偏光模组的基底，能够降低显示装置的厚度，有利于柔性超薄的实现，能够实现显示装置的可弯折。

本实施例中，对于偏光模组09内部来说，可以通过自然附着或增加层间介质层的方式将相位延迟层02与所述线性偏光层03结合，因为层间介质层一般采用无机绝缘材料，膜厚在几十nm到几百nm之间，远小于贴合胶层01的厚度，因此，可以降低偏光模组09的厚度，实现偏光模组09的柔性超薄。
一些实施例中，如图7所示，所述相位延迟层02与所述线性偏光层03直接接触；或，如图4-图6所示，所述相位延迟层02与所述线性偏光层03之间设置有层间介质层05，通过层间介质层05结合在一起，其中，所述层间介质层05的厚度可以不大于500nm，比如可以为10-50nm，层间介质层05可以采用极性介于线性偏光层03与相位延迟层02之间的有机或无机化合物。
