Display apparatus
A display apparatus includes: a housing, a display panel, a cover panel, a first adhesive, the housed member, the second adhesive, and a protrusion. The display panel is arranged in a position corresponding to an opening of the housing, and has a front surface and a back surface. The cover panel covers the front surface. The first adhesive glues the housing and the cover panel together. The housed member is located adjacent to the back surface of the display panel and is housed in the housing. The second adhesive glues a rim portion of the back surface of the display panel and the housed member together. The protrusion is located on a portion of one of the housed member and the display panel, and protrudes toward the other of the housed member and the display panel. The portion corresponds to a location of the second adhesive on the other.
1 . A display apparatus comprising:
a housing that includes an opening;
a display panel that is arranged in a position corresponding to the opening of the housing, the display panel having a front surface and a back surface that faces in an opposite direction than the front surface faces;
a cover panel that covers the front surface of the display panel;
a first adhesive that glues a first surface of the housing to a second surface of the cover panel to glue the housing and the cover panel together;
a housed member that is located adjacent to the back surface of the display panel and is housed in the housing;
a second adhesive that glues a rim portion of the back surface of the display panel and the housed member together; and
a protrusion that is provided on a portion of the housed member that faces the rim portion of the back surface of the display panel, the protrusion protruding toward the rim portion, and the second adhesive being disposed between the protrusion and the rim portion of the back surface of the display panel, wherein
the protrusion is not located in positions corresponding to a starting point from which application of the second adhesive starts and an end point at which the application of the second adhesive ends, and the protrusion is not located in a gap between the starting point and the end point of the second adhesive.
2 . The display apparatus according to claim 1 , wherein
the protrusion is a rib that extends along a circumferential direction of the housed member.
3 . The display apparatus according to claim 1 , wherein
a space is formed between the protrusion and the rim portion of the back surface of the display panel, and
the second adhesive is positioned in the space.
4 . The display apparatus according to claim 3 , further comprising:
an abutting portion that is located on at least one of the second surface of the cover panel and the first surface of the housing that are glued to each other by the first adhesive, the abutting portion projecting from the one of the first and second surfaces and abutting the other of the first and second surfaces, wherein
the cover panel is joined to the display panel, and
relative positions of the cover panel and the housing are determined by the abutting portion abutting the other of the second surface of the cover panel and the first surface of the housing so that the space is formed between the protrusion and the rim portion of the back surface of the display panel, the second adhesive being located in the space.
5 . The display apparatus according to claim 1 , wherein
the protrusion has a tip portion and a base portion, and a width of the tip portion is smaller than a width of the base portion in a cross-section in a protruding direction of the protrusion.
6 . The display apparatus according to claim 5 , wherein
the protrusion is formed such that the cross-section in the protruding direction of the protrusion is in a shape of a trapezoid, a triangle or a hemisphere.
7 . The display apparatus according to claim 1 , wherein
the first adhesive is identical to the second adhesive.
8 . The display apparatus according to claim 1 , wherein
the housed member is a backlight unit that includes a frame and irradiates the display panel with light, and
the second adhesive glues the rim portion of the back surface of the display panel and the frame of the backlight unit together.
9 . The display apparatus according to claim 1 , wherein
a portion of a back surface of the cover panel is adhered to the front surface of the display panel by an optically clear resin.
10 . The display apparatus according to claim 1 , wherein
a width of the second adhesive is greater than a width of the protrusion.
11 . A display apparatus comprising:
a housing that includes an opening;
a display panel that is arranged in a position corresponding to the opening of the housing, the display panel having a front surface and a back surface that faces in an opposite direction than the front surface faces;
a cover panel that covers the front surface of the display panel;
a first adhesive that glues a first surface of the housing to a second surface of the cover panel to glue the housing and the cover panel together;
a housed member that is located adjacent to the back surface of the display panel and is housed in the housing;
a second adhesive that glues a rim portion of the back surface of the display panel and the housed member together; and
a protrusion that is provided on a portion of the housed member that faces the rim portion of the back surface of the display panel, the protrusion protruding toward the rim portion, and the second adhesive being disposed between the protrusion and the rim portion of the back surface of the display panel, wherein
the protrusion has a different shape at a starting point and at an end point at which application of the second adhesive starts and ends, as compared to positions other than the starting point and the end point of the application of the second adhesive, and the protrusion has the different shape in a gap between the starting point and the end point of the second adhesive.
12 . The display apparatus according to claim 11 , wherein
a height of a portion of the protrusion having the different shape in the gap is less than a height of a remainder of the protrusion.
13 . The display apparatus according to claim 12 , wherein
a width of a portion of the protrusion having the different shape in the gap is less than a width of a remainder of the protrusion.
14 . The display apparatus according to claim 11 , wherein
a width of a portion of the protrusion having the different shape in the gap is less than a width of a remainder of the protrusion.
