DISPLAY PANEL
First Claim
1. A display panel comprising a substrate and a display medium layer held on the substrate, said display panel having a display region and a frame region outside the display region and including a hole on an inner side of the frame region penetrating the substrate and the display medium layer, the display panel further comprising:
- a hole-periphery sealing part disposed on the substrate at a side facing the display medium layer so as to surround the hole,wherein the hole-periphery sealing part is made of;
a first sealing member having a broken loop shape, surrounding the hole, having at least one open section; and
at least one second sealing member provided at a location corresponding to said at least one open section so as to seal said at least one open section.

Abstract
A display panel includes a substrate and a display medium layer held on the substrate and has a display region and a frame region outside the display region and a hole on an inner side of the frame region penetrating the substrate and the display medium layer. The display panel further includes a hole-periphery sealing part disposed on the substrate at a side facing the display medium layer so as to surround the hole, in which the hole-periphery sealing part is made of: a first sealing member having a broken loop shape, surrounding the hole, having at least one open section; and at least one second sealing member provided at a location corresponding to the one open section so as to seal said at least one open section.

4. A display panel comprising a substrate and a display medium layer held on the substrate, said display panel having a display region and a frame region outside the display region and including a hole on an inner side of the frame region penetrating the substrate and the display medium layer, the display panel further comprising:
a hole-periphery sealing part formed by expanding, in a planar direction, a sealing member having a dot shape or a planar shape that is provided, before the hole is formed, at a location on the substrate where the hole is to be formed until the sealing member reaches a restricting structure that hinders the expansion of the sealing member so that after drilling the hole, the hole-periphery sealing part has a loop shape of the sealing member bordered by the restricting structure. - View Dependent Claims (5)

6. An intermediate panel for manufacturing a display panel, the intermediate panel comprising an upper substrate, a lower substrate, and a display medium layer held between the upper and lower substrates, said intermediate panel having a display region and a frame region outside the display region and having an area on an inner side of the frame region in which a hole penetrating the substrate and the display medium layer is to be formed, the intermediate panel further comprising:
-
a hole-periphery sealing part covering the area in which the hole is to be formed, wherein the hole-periphery sealing part is made of;
a first sealing member on the lower substrate having a round shape covering the area in which the hole is to be formed; and
at least one second sealing member provided on the upper substrate pressing down a part of the round shape defined by the first sealing member. - View Dependent Claims (7)
