  FIG. 6 is a top view of the horizontal portion 410 of the guide frame 400 on which the main adhesive member 510 and the auxiliary adhesive member 520 are formed.

  The main adhesive member 510 is formed between the regions where the auxiliary adhesive members 520 are formed. At this time, the auxiliary adhesive member 520 is a kind of dam (DAM) or wall so as to prevent a problem that the liquid adhesive of the main adhesive member 510 is diffused to the outside by pressure bonding when the display panel 100 and the guide frame 400 are joined. (WALL) role.

  When bonding without the auxiliary adhesive member 520, the liquid adhesive can be diffused to the outside, and the outer frame portion of the display panel 100 is widened to minimize defects due to diffusion. Is effective in minimizing the frame width by minimizing the bonding width of the liquid adhesive.

  Although FIG. 6 shows the auxiliary adhesive member 520 formed on both side surfaces of the main adhesive member 510, the formation position and shape are not limited thereto. According to another embodiment, the liquid adhesive may be formed only on the outer side surface of the main adhesive member 510 to prevent the liquid adhesive from diffusing outside in order to minimize the outer frame.

  In addition, when the display panel 100 is fixed without a gap, the display panel 100 may be locally deformed due to a difference in coefficient of thermal expansion or the like according to the external temperature, and the light emitted from the backlight 200 may be changed. Since the path is deformed, the light leakage phenomenon which is a weak point of the liquid crystal display device is likely to occur. Therefore, in order to prevent this, the main adhesive member 510 is preferably formed with a certain height and expansion / contraction because the display panel 100 has a gap.

  The height of the auxiliary adhesive member 520 after curing is lower than the cured height of the main adhesive member 510. The main adhesive member 510 comes into direct contact with the lower surface of the display panel 100, and the auxiliary adhesive member 520 has a gap without coming into contact with the display panel 100.

  The auxiliary adhesive member 520 prevents the liquid adhesive of the main adhesive member 510 from overflowing and diffusing outside, and restricts the movement of the display panel 100 along the Z axis.

  Although the movement of the display panel 100 is necessary for minimizing light leakage and impact, if the display panel 100 is pushed excessively in the direction of the guide frame 400, the parts are in direct contact with both parts. May cause a problem of damage, and may cause problems such as unwanted light leakage.

  Therefore, in order to minimize this problem, the auxiliary adhesive member 520 is formed at a certain height, and the height of the cured auxiliary adhesive member 520 is a height at which the maximum pressure can be applied to the auxiliary adhesive member 520. Limited to

  The auxiliary adhesive member 520 is higher than the adhesive material of the main adhesive member 510 in order to give the main adhesive member 510 a gap due to adhesion and expansion / contraction between the display panel 100 and the guide frame 400 and prevent damage due to pressing. It is characterized by being a high-viscosity adhesive with hardness.

  Each of the above-described embodiments of the display device according to the present invention has been described as including a display panel 100 and a backlight unit 200 and constituting a liquid crystal display product. However, the display device according to the present invention is not necessarily limited thereto, and the display panel 100 may be replaced by an organic light emitting display panel (Organic Light Emitting Display Panel) including organic light emitting elements. In this case, since the organic light emitting display panel is a self light emitting element, the backlight unit 200 may be omitted.

  In this case, the display panel 100 including the organic light emitting display panel may include a lower substrate and an upper substrate that is bonded to the lower substrate.

  The lower substrate includes a plurality of light emitting cells formed for each region defined by a gate line, a data line, and a power line. Each of the plurality of light emitting cells emits light by at least one switching transistor connected to the gate line and the data line, at least one driving transistor connected to the switching transistor and the power line, and a flow controlled by switching of the driving transistor. A light emitting element may be included.

  The upper substrate is oppositely bonded to the lower substrate to protect the light emitting device formed on the lower substrate. At this time, the upper substrate may include a light emitting device connected to the driving transistor formed on the lower substrate. In this case, the light emitting device formed on the lower substrate is omitted.

Can only be formed.

  The main adhesive member 510 may be formed of the same material as the auxiliary adhesive member 520, but may have different viscosities, which may cause problems such as damage to the display panel 100 due to impact and light leakage. In order to minimize the thickness of the auxiliary adhesive member 510, it may be formed to have a lower viscosity than the material of the auxiliary adhesive member 510 serving as a support.

  Next, as can be seen from FIG. 7d, the guide frame 400 and the display panel 100 are coupled. Since the main adhesive member 510 is in contact with the display panel 100 and the guide frame 400, the main adhesive member 510 is cured and the display panel 100 is bonded to the guide frame 400. Depending on the adhesive material of the main adhesive member 510, it is cured after a preset time at room temperature, cured by applying heat at a preset temperature, or cured by irradiating ultraviolet rays.
