The pair of dams 129a and 129b constrain the diffusion region of the fixer adhesive member 130 when the fixer 120 and the display panel 110 are adhered to each other, And is prevented from diffusing toward the outer side.

In order to evaluate the adhesion characteristics between the fixer and the display panel according to the embodiment of the present invention, three fixers according to the comparative example, the first embodiment and the second embodiment were produced as shown in Table 1 below.

In Table 1, the comparator of the comparative example is a hole in which no holes are formed, the filler of Example 1 is a filler having holes shown in Figs. 3 and 4, and the filler of Example 2 is the filler of Fig. It is a fixer in which a hole with a trapezoidal shape is formed.

For each sample of the above-mentioned pickers, in order to measure the adhesive force property, a fixer is adhered to the adhesive resin applied to the organic substrate and then cured, and then the pusher The force at the time when the fixer peeled off from the glass substrate was measured.

As can be seen from Table 1, it can be seen that the adhesive strength of the filler according to Examples 1 and 2 of the present invention is higher than that of the comparative example in both the minimum adhesive strength and the maximum adhesive strength. It can be seen that the contact area (or adhesion) area between the fixture adhesive and the fixer is increased by the adhesive filling part 126 formed on the fixer, thereby increasing the adhesive strength.

Although the display panel 110 is a liquid crystal display panel including a liquid crystal layer in the display device 100 according to an embodiment of the present invention, And may be replaced with an organic light emitting display panel including a light emitting device. In this case, since the organic light emitting display panel is a self-light emitting device, the backlight unit 140 housed in the panel supporting unit 150 may be omitted.

The display panel 110 composed of the organic light emitting display panel includes a lower substrate 112 and an upper substrate 114 which is adhered to the lower substrate 112.

The lower substrate 112 includes a plurality of light emitting cells formed in regions defined by a gate line, a data line, and a power source line. Each of the plurality of light emitting cells includes 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 supply line, and a light emitting element As shown in FIG.

The upper substrate 114 is adhered to the lower substrate 112 to protect the light emitting device formed on the lower substrate 112. In this case, the upper substrate 114 may include a light emitting element connected to a driving transistor formed on the lower substrate 112. In this case, the light emitting element formed on the lower substrate 112 is omitted.

The display panel 110 composed of the organic light emitting display panel may further include the upper polarizing member 118 described above.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents. Will be clear to those who have knowledge of.
