Problems solved by technology

In the worst case, the resin spreads to the back of the panel and the illuminated side of the backlight, which may cause poor display, and may also cause problems with uncured OCR leaking from the display module
[0013] Or even when the frame portion and the resin dam portion are bonded and fixed by the normally formed dam portion, the panel and the frame portion may temporarily move up and down, respectively, during the bonding step, transportation step, etc., resulting in The adhesion between the resin dam and the resin dam part is broken, and a seepage path to the inside of the module is also temporarily formed

Embodiment 1

[0071] exist Figure 1 to Figure 4 The configuration of the liquid crystal display device in the first embodiment (Example 1) is shown in . figure 1 is a schematic diagram showing the structure of the display module in this embodiment.

[0072] The display module 101 according to the present embodiment includes: an LCD panel 102 as a display panel including an upper substrate and a lower substrate (CF substrate (color filter substrate) and TFT substrate) bonded together; a backlight unit 103 as a A case portion for accommodating the above-described upper substrate and lower substrate; and a frame portion 104 having an opening corresponding to the display surface D and mounted in the backlight unit 103, wherein the resin flow suppressing member B1 is placed in the frame portion 104 is disposed between the LCD panel 102 and the bezel portion 104 over the entire periphery thereof.

[0073] figure 2 is in figure 1 The schematic diagram and A-A' cross-sectional view of the a...

Embodiment 2

[0090] Hereinafter, a second embodiment (Example 2) will be explained. In the drawings, items common to the first embodiment will be omitted or shown by the same reference numerals as the last two digits of the reference numerals (hereinafter, the same applies to other embodiments).

[0091] In the second embodiment, unlike the first embodiment, a resin flow suppressing member B2 ( Figure 5 ). The resin flow suppressing member B2 is arranged in the vicinity of the opening end 204e on the rear surface of the frame portion 204, whereby it is possible to suppress the resin bank portion 207 from being dented in its formation and reduce the formation failure of the resin bank portion 207.

[0092] Even when the above-mentioned resin bank 207 is not normally formed, the resin bank 207 and the resin flow suppressing member B2 must be arranged in positions sufficiently close to each other so that they come into contact. In the case of this embodiment, the resin flow suppressing mem...

Embodiment 3

[0094] In embodiment 3 of the present invention, as Figure 6 As shown in , a resin flow suppressing member B1 having OCR absorbing performance is arranged on both the rear surface of the bezel portion 304 and the surface of the LCD panel 302 with a gap provided therebetween. In the case of this embodiment, a larger contact area of ​​the leaked OCR 305 and the resin flow suppressing member B1 can be ensured, and thus the leaked OCR can be more surely and quickly prevented from spreading.

Abstract

A display device includes a front panel wholly bonded on a display part of a display module via OCR (a transparent optical elastomeric resin). If a dam for preventing the OCR from being infiltrated is overflowed, the OCR is inhibited from being infiltrated and diffused into an inside of the module. The display device includes a display module including upper and lower substrates, a case receiving the upper and lower substrates, and a bezel with an opened display part, mounted in the case part, and further including a front panel wholly bonded on a display part of the display module described above via a transparent optical elastomeric resin, and a resin dam disposed on a surface of the upper substrate along an open end of a reverse side of the bezel part, wherein at least a part of the resin dam is apart from the bezel part.

Description

technical field [0001] The present invention relates to a display device, and more particularly, to a display device equipped with a front panel such as a touch panel. Background technique [0002] In recent years, for a liquid crystal display module as a display device, a display device in which an input interface component such as a touch panel is installed, and in which is installed such as from the viewpoint of design performance and protection of the display surface And the front panel is decorated and printed tempered glass. [0003] When a front panel such as a touch panel is installed in a liquid crystal display module, an air layer usually exists between the surface of the liquid crystal panel in the module and the touch panel, so due to the difference in the refractive index of the touch panel (for example, glass The optical properties in the interface between the substrate) and the air layer, so light is reflected. [0004] Due to the interface reflection in the...
