Substrate processing apparatus and display device using the same

The invention provides a substrate processing apparatus and display device using the same. Various embodiments provide a substrate processing apparatus for grinding a substrate, and a display device including a substrate in which a hole is formed in an edge of the substrate using the substrate processing apparatus. The substrate processing apparatus for processing a display substrate includes a body which, in operation, rotates, a cylindrical grinding part connected to the body, and a lateral groove formed in a surface of the cylindrical grinding part. The lateral groove is configured to accommodate the display substrate. Thus, it is possible to form a hole by grinding an edge of the display substrate so as to be matched with a designed value. 基板处理装置和使用其的显示设备。提供了种用于研磨基板的基板处理装置和包括使用基板处理装置在基板的边缘中形成孔的基板的显示设备。用于处理显示基板的基板处理装置包括：主体，所述主体在操作中旋转；圆柱形研磨部，所述圆柱形研磨部连接到所述主体；和横向槽，所述横向槽位于所述圆柱形研磨部的表面中，所述横向槽容纳待处理的所述显示基板。因此，通过研磨显示基板的边缘可以形成孔以便与设计值相匹配。
