Electronic apparatus, method of producing electronic apparatus, and substrate laminate

An electronic apparatus, comprising:

• a translucent first substrate having a first bond surface;
• a second substrate facing the first bond surface;
• a housing having a storage that stores the second substrate, and having a second bond surface that is arranged around the storage and that includes a portion facing an outer periphery of the first bond surface;
• a first bond layer that bonds the first substrate and the second substrate together and is made of a cured product of a light-curable resin;
• a second bond layer that bonds the outer periphery of the first bond surface and the second bond surface together;
• and
• a guard arranged on the first bond surface along at least a part of the periphery of the first bond layer and having a structural surface with a lower wettability to the light-curable resin than that of the first bond surface,
• wherein the guard has a first edge and a second edge opposite the first edge,
• wherein the first bond layer has a first bonding surface in contact with the first edge of the guard, and has a second bonding surface opposite the first bonding surface and in contact with the second bond surface, and
• wherein the lower wettability of the light-curable resin to the structural surface of the guard prevents movement of the light-curable resin, such that the first bond layer is not in contact with the second edge of the guard, and such that the first bond layer does not extend beyond a periphery of the second bond surface in an absence of a structural guard at the periphery of the second bond surface.

A method of producing an electronic apparatus, comprising:

• forming a frame-shaped coating at a periphery of a first surface of a translucent substrate;
• forming a guard having a structural surface with a light-curable resin has a lower wettability to the structural surface of the guard than a wettability of the light-curable resin to the coating formed on the first surface, the guard being formed at least a part between an inner periphery and an outer periphery of the coating, and the guard having a first edge and a second edge opposite the first edge;
• applying the light-curable resin on the first surface of the translucent substrate at an inner-periphery side of the coating;
• bonding a display panel to the first surface via the light-curable resin, the display panel including a display surface in contact with light-curable resin during the bonding;
• and
• curing the light-curable resin by irradiating the light-curable resin with light through a second surface opposite to the first surface to produce a bond layer having a first bonding surface in contact with the first edge of the guard, and having a second bonding surface opposite the first bonding surface and in contact with the display surface,
• wherein, during the curing, the lower wettability to the guard deters movement of the light-curable resin, such that the bond layer does not contact with the second edge of the guard, and such that bond layer does not extend beyond a periphery of the display surface in an absence of a structural guard at the periphery of the display surface.

A substrate laminate, comprising:

• a translucent first substrate having a first bond surface;
• a second substrate having a second bond surface facing the first bond surface;
• a bond layer that bonds the first substrate and the second substrate together and is made of a cured product of a light-curable resin;
• and
• a guard arranged on the first bond surface along at least a part of a periphery of the first bond surface and having a structural surface such that the light-curable resin has a lower wettability to the structural surface of the guard than a wettability of the light-curable resin to the first bond surface,
• wherein the guard has a first edge and a second edge opposite the first edge,
• wherein the bond layer has a first bonding surface in contact with the first edge of the guard, and has a second bonding surface opposite the first bonding surface and in contact with the second bond surface, and
• wherein the lower wettability of the light-curable resin to the structural surface of the guard prevents movement of the light-curable resin, such that the bond layer is not in contact with the second edge of the guard, and such that the bond layer does not extend beyond a periphery of the second bond surface in an absence of a structural guard at the periphery of the second bond surface.
