For example, the refractive index may be about 1.475 and the transmittance may be about 90.2%, and a difference in refractive index from the window 251a may be smaller than that of air, thereby improving visibility of the display panel 251b.

By using the surface tension of the fluid oil, the window 251 may be coupled to the display panel 251 b in the thickness direction. As a fluid oil, when a volatile oil such as a silicone oil is used, the window portion 251 can be detachably coupled to the display panel 251 b semi-permanently. In addition, when a defect occurs in either the display panel 251b or the touch sensing pattern layer 251c, any one can be easily replaced, thereby reducing the cost. This advantage is noticeable in the case of using an ITO film with a relatively high defect rate.
