I understood. More specifically, when the translucent cover 20 is formed of a general resin material (refractive index of about 1.5) such as an acrylic resin, the thickness of the translucent cover 20 is the maximum frame width. It is preferable that the thickness is set to about 2.7 to 4.6 times the thickness. This is one of the conditions for making it difficult to see the frame area confirmed by the present inventors.
- the thickness of the translucent cover is determined. That is, if it is difficult to visually recognize only the side frame by ignoring the corner frame, the thickness is about 2.7 to 4.6 times the larger one of the widths a1 and a2.
- the thickness of the translucent cover may be set. However, if the frame region is to be hidden even at the corner, the translucent cover has the maximum frame width (a1 2 + a2 2 ) 1 / The thickness is set to be 2.7 to 4.6 times that of 2 . For this reason, the translucent cover becomes thick, and the weight may increase or the feeling of depth may increase.
