Description

显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种显示装置。
 背景技术
现在的显示设备如LCD（Liquid Crystal Display）液晶显示器、OLED（Organic Light-Emitting Diode）有机电激光显示屏等，都需要用到偏光片POL来实现对液晶进行控制来调节光线的强度。
如图1所示，显示设备在进行组装时，在非显示区NA内，将柔性电路板FPC11绑定在触控面板12上，然后将偏光片POL13贴合覆盖在触控面板12和柔性电路板FPC11上，因为在绑定时，柔性电路板FPC11与触控面板12存在断差，这将导致偏光片POL13贴合后，与触控面板12之间存在气泡，后期该气泡会进入显示区AA内，影响显示效果。
即，现有显示设备存在偏光片与触控面板之间的气泡进入显示区的技术问题，需要改进。
