Display device
View Patent ↗According to an aspect, a display device includes: a substrate including a pixel portion and a terminal portion that are provided on a first surface of the substrate, a flexible printed circuit board that is bonded to the terminal portion, a polarizing plate that is bonded to a region facing the pixel portion in a second surface opposite to the first surface of the substrate, a support member that is bonded to a region facing the terminal portion in the second surface, and a covering member that is bonded to the polarizing plate and the support member.
1. A display device comprising:
a substrate having a first surface and a second surface, the first surface including a pixel portion and a terminal portion, and the second surface being opposite to the first surface and facing an observer's side;
a flexible printed circuit board that is electrically coupled to the terminal portion;
a polarizing plate that is bonded to the second surface in a region facing the pixel portion;
a support member that is bonded to the second surface in a region facing the terminal portion; and
a covering member that is bonded to the polarizing plate and the support member,
wherein
on the first surface of the substrate in the terminal portion, one end of the flexible printed circuit board is disposed, and
on the second surface of the substrate, a layer including the support member and the polarizing plate is disposed.
2. The display device according to claim 1 , wherein
the polarizing plate is provided so as to extend over a region facing the pixel portion and a region facing the terminal portion, and
the polarizing plate provided to the region facing the terminal portion is configured as the support member.
3. The display device according to claim 1 , wherein
the flexible printed circuit board is bonded to the terminal portion with a conductive bonding layer, and
the support member is bonded to a region of the second surface facing the conductive bonding layer.
4. The display device according to claim 1 , wherein
an IC chip is electrically coupled to the terminal portion, and
the support member is bonded to a region facing the IC chip in the second surface.
5. The display device according to claim 1 , wherein a thickness of the support member is equal to a thickness of the polarizing plate.
6. The display device according to claim 1 , wherein
the covering member has a curved surface portion that is curved, and
the substrate is bonded to the curved surface portion through the polarizing plate and the support member.
7. The display device according to claim 1 , wherein
the substrate is a glass substrate having a thickness of 50 μm to 200 μm.
8. The display device according to claim 1 , wherein the substrate and the layer including the support member and the polarizing plate are all curved along the covering member and bonded tightly to the covering member.
9. The display device according to claim 1 , further comprising a backlight that is opposed to the substrate, wherein
the backlight, the one end of flexible printed circuit board, the substrate, the layer including the support member and the polarizing plate, and the covering member are provided in that order.
10. The display device according to claim 1 , wherein the terminal portion of the substrate is fixed to the covering member through the support member.
