Display device
View Patent ↗According to one embodiment, provided is a display device with an improved manufacturability which is capable of preventing a decrease in the display quality due to a change in the gap between an array substrate and a counter substrate caused by a temperature change. The primary bonding portion is composed of translucent synthetic resin and provided to bond together the counter substrate side and a touch panel side in a manner covering at least a display area. The secondary bonding portion is provided in a columnar shape through curing of adhesive being ultraviolet curable liquid resin with a viscosity higher than that of the synthetic resin of the primary bonding portion, the secondary bonding portion bonding together the non-opposed portion side and the touch panel side.
1. A display device comprising:
a display device main body configured to display an image thereon;
a transparent touch panel including a sensor portion and a protector cover; and
a bonding portion bonding the display device main body and the touch panel to each other, wherein
the display device main body comprises:
a first substrate;
a second substrate disposed with a predetermined clearance maintained with respect to the first substrate in a manner opposed to a portion of the first substrate, the second substrate arranged to form with the first substrate a display area therebetween capable of displaying an image therein;
a peripheral portion provided at a position of the first substrate not opposed to the second substrate, and
a driver mounted on the peripheral portion and electrically connected with the display area, and wherein
the bonding portion comprises:
a primary bonding portion composed of translucent synthetic resin and bonding together the second substrate side and the sensor portion in a manner covering at least the display area; and
a secondary bonding portion provided in a columnar shape through curing of adhesive being ultraviolet curable liquid resin with a viscosity higher than that of the synthetic resin of the primary bonding portion, the secondary bonding portion being disposed on the driver and bonding together the peripheral portion side and a side surface of the sensor portion and the protector cover, wherein
the primary bonding portion is thinner than the secondary bonding portion in film thickness, and
the secondary bonding portion is positioned separated away from the primary bonding portion.
2. The display device according to claim 1 , wherein the secondary bonding portion is provided through curing of at least one point applied of the adhesive.
3. The display device according to claim 1 , wherein the secondary bonding portion is provided through curing of at least one line applied of the adhesive.
4. The display device according to claim 1 , wherein
the display device main body comprises a spacer disposed on the peripheral portion outside of the driver, and wherein
one or more secondary bonding portions are disposed on the driver and the spacer.
5. The display device according to claim 1 , wherein the display device main body is a liquid crystal panel.
