(liquid crystal display panel 10)
Fig. 4 is a plan view of the liquid crystal display panel 10.
The liquid crystal display panel 10 includes substrates 11 and 12, polarizers 13 and 14, and a driver 15. A liquid crystal layer and the like are disposed between the substrates 11 and 12. In fig. 2 and 3, the components between the substrates 11 and 12 are not shown. The polarizing plate 13 is laminated on one main surface of the substrate 11. The polarizing plate 14 is laminated on one main surface of the substrate 12. An actuator 15 is disposed at an end of the substrate 11 in the Y direction.
Fig. 5 is a cross-sectional view showing an example of the liquid crystal display panel 10.
The liquid crystal display panel 10 includes: a TFT substrate 11 on which switching elements, pixel electrodes, and the like are formed; and a color filter substrate (CF substrate) 12 formed with a color filter, a common electrode, and the like and disposed to face the TFT substrate 11. The TFT substrate 11 and the CF substrate 12 are each formed of a transparent substrate (e.g., a glass substrate or a plastic substrate). The TFT substrate 11 is disposed opposite to the backlight 20, and illumination light from the backlight 20 enters the liquid crystal display panel 10 from the TFT substrate 11 side. Of the 2 main surfaces of the liquid crystal display panel 10, the main surface on the opposite side to the backlight 20 is a display surface of the liquid crystal display panel 10.
The liquid crystal layer 40 is filled between the TFT substrate 11 and the CF substrate 12. Specifically, the liquid crystal layer 40 is sealed in a region surrounded by the TFT substrate 11, the CF substrate 12, and a sealing material (not shown) for bonding them. The sealing material is formed of, for example, an ultraviolet-curable resin, a thermosetting resin, or a uv/heat-curable resin, and is applied to the TFT substrate 11 or the CF substrate 12 in the manufacturing process and then cured by irradiation with ultraviolet rays or heating.
The liquid crystal material constituting the liquid crystal layer 40 changes optical characteristics by manipulating the orientation of liquid crystal molecules in response to an electric field applied between the TFT substrate 11 and the CF substrate 12. As the liquid crystal mode, various liquid crystal modes such as a va (vertical alignment) mode, a tn (twisted chemical) mode, and a homogeneous mode can be applied.
A plurality of switching elements (active elements) 41 are provided on the liquid crystal layer 40 side of the TFT substrate 11. As the switching element 41, for example, a TFT (thin Film transistor) is used, and an n-channel TFT is used. The TFT4 includes: a gate electrode functioning as a scan line; a gate insulating film disposed over the gate electrode; a semiconductor layer (e.g., an amorphous silicon layer) disposed over the gate insulating film; and a source electrode and a drain electrode which are locally in contact with the semiconductor layer and are provided separately from each other. The source electrode is electrically connected to the signal line.
An insulating layer 42 is provided over the TFT 41. A plurality of pixel electrodes 43 corresponding to the respective pixels are provided on the insulating layer 42. In the insulating layer 42 and over the drain electrode of the TFT41, a contact plug (contact hole) 44 electrically connected to the pixel electrode 43 is provided.
A color filter 45 is provided on the liquid crystal layer 40 side of the CF substrate 12. The color filter 45 includes a plurality of coloring filters (coloring members), specifically, a plurality of red filters 45-R, a plurality of green filters 45-G, and a plurality of blue filters 45-B. A general color filter is composed of three primary colors of light, i.e., red (R), green (G), and blue (B). The composition of three colors of R, G, B adjacent to each other is a unit of display (pixel), and a portion of R, G, B in one pixel, which is any one color, is a minimum driving unit called a sub-pixel (sub). The TFT41 and the pixel electrode 43 are provided for each sub-pixel.
A black matrix (light-shielding film) 46 for shielding light is provided at the boundary portion between the red filter 45-R, the green filter 45-G, and the blue filter 45-B and at the boundary portion between the pixels (sub-pixels). That is, the black matrix 46 is formed in a mesh shape. The black matrix 46 has a function of, for example, shielding unnecessary light between the coloring members to improve contrast.
A common electrode 47 is provided on the color filter 45 and the black matrix 46. The common electrode 47 is formed in a planar shape in the entire display region of the liquid crystal display panel 10.
A polarizer 13 is laminated on the TFT substrate 11 opposite to the liquid crystal layer 40, and a polarizer 14 is laminated on the CF substrate 12 opposite to the liquid crystal layer 40. The polarizing plate 13 and the polarizing plate 14 are disposed in a cross-nicol state in which transmission axes thereof are orthogonal to each other. An 1/4 wavelength plate may be provided between the TFT substrate 11 and the polarizing plate 13. An 1/4 wavelength plate may be provided between the CF substrate 12 and the polarizing plate 14.
The pixel electrode 43, the contact plug 44, and the common electrode 47 are formed of a transparent electrode, and ITO (indium tin oxide) is used, for example. As the insulating layer 42, a transparent insulating material, for example, silicon nitride (SiN) is used.
(backlight 20)
The backlight 20 is, for example, of a side light type (edge light type). As shown in fig. 1 to 3, the backlight 20 includes a light source 21, a reflective sheet 22, a light guide plate 23, a diffusion sheet 24, and prism sheets 25 and 26. The reflective sheet 22, the light guide plate 23, the diffusion sheet 24, and the prism sheets 25 and 26 are stacked in this order.
The light source unit 21 includes, for example, a plurality of light emitting elements. Each of the plurality of light emitting elements is formed of, for example, an LED (light-emitting diode). The light source unit 21 emits light toward the side surface of the light guide plate 23. A fluorescent lamp such as a cold cathode tube may be used as the light source unit 21.
The light guide plate 23 guides light emitted from the light source unit 21 to the liquid crystal display panel 10 side, and emits the light to the liquid crystal display panel 10 side.
The reflection sheet 22 reflects the light emitted from the back surface of the light guide plate 23 toward the light guide plate 23 again. That is, the reflection sheet 22 reuses light emitted from the rear surface of the light guide plate 23.
The diffusion sheet 24 uniformly diffuses light to reduce the spot of the surface light source.
The prism sheets 25 and 26 condense light in the front direction, thereby improving front luminance. The prism sheets 25 and 26 are arranged so that the directions of refraction of light are orthogonal to each other. The presence or absence of the prism sheets and the number of prism sheets can be arbitrarily set.
(adhesive member 31)
Fig. 6 is a plan view of the adhesive member 31 extracted. In fig. 6, the outline of the backlight 20 is shown by a dotted line.
The adhesive member 31 adheres the backlight 20 and the liquid crystal display panel 10. The adhesive member 31 has a square frame shape and is disposed so as to surround the display region of the liquid crystal display panel 10. The inside of the adhesive member 31 is a region through which light from the backlight 20 passes.
A gap 33 is provided between the backlight 20 and the liquid crystal display panel 10. The gap 33 corresponds to an area inside the adhesive member 31. The length of the gap 33 in the stacking direction corresponds to the thickness of the adhesive member 31.
The adhesive member 31 has light-shielding properties and suppresses the incidence of unnecessary display light on the liquid crystal display panel 10.
Fig. 7 is a sectional view of the adhesive member 31. The adhesive member 31 includes a light shielding member 31A and adhesive members 31B and 31C.
The light shielding member 31A is made of, for example, a resin containing a black dye (black resin). The adhesive members 31B and 31C are made of, for example, a sealing material. The adhesive 31B adheres to the backlight 20 and the frame 30. The adhesive material 31C is adhered to the liquid crystal display panel 10.
The adhesive member 31 has a notch 32 recessed from the inside toward the outside. The cutout portion 32 has a square shape, for example.
The cutout 32 is disposed, for example, on a side of the adhesive member 31 corresponding to the side of the liquid crystal display panel 10 on which the driver 15 is disposed, and at an end of the side. The position of the notch 32 can be arbitrarily set. The notch 32 is preferably disposed at a position that has little influence on display.
The cutout 32 is configured to extend across the boundary between the backlight 20 and the frame 30. The function of the notch 32 will be described later.
(frame 30)
Fig. 8 is a plan view with the frame 30 extracted.
The frame 30 fixes the backlight 20 and the liquid crystal display panel 10. The frame 30 has a four-square-box shape. The frame 30 is made of resin.
The frame 30 has a step 30A. The size of the opening 30B below the step 30A in the frame 30 is set to be the same as or slightly larger than the size of the backlight 20, and the backlight 20 is embedded in the opening 30B in this portion. The size of the opening 30B above the step 30A in the frame 30 is set to be the same as or slightly larger than the size of the liquid crystal display panel 10, and the liquid crystal display panel 10 is fitted into the opening 30B in this portion.
The adhesive member 31 is adhered to the step 30A of the frame 30. Thus, the backlight 20, the liquid crystal display panel 10, and the frame 30 are fixed by the adhesive member 31.
(case 34)
The housing 34 accommodates the frame 30. The housing 34 has a square shape. The inside of the housing 34 is sized to be the same as or slightly larger than the outer shape of the frame 30. The housing 34 is constructed of metal.
[1-2] function of notch 32
Next, the operation of the notch 32 provided in the adhesive member 31 will be described. Fig. 9 is a sectional view of adhesive member 31 with notch 32 at the center.
The cutout 32 extends toward the frame 30 side from an end of the backlight 20 (corresponding to a boundary between the backlight 20 and the frame 30). Therefore, in the region of the cutout 32, a passage of air is provided which reaches the boundary between the backlight 20 and the frame 30 from the gap 33. In fig. 9, the passage of air is indicated by dashed arrows.
In the present embodiment, by providing the notch 32 in the adhesive member 31, the gap 33 between the backlight 20 and the liquid crystal display panel 10 can be prevented from being sealed.
The liquid crystal display device 1 in the state shown in fig. 1 to 3 is assembled, and then a step of attaching a touch panel to the liquid crystal display panel 10 is performed. In the step of attaching the touch panel, the liquid crystal display device 1 is placed in a depressurized environment (for example, a vacuum environment). In this case, when the gap 33 between the backlight 20 and the liquid crystal display panel 10 is sealed, the liquid crystal display panel 10 warps. Thereby, the liquid crystal display device 1 expands or contracts.
In addition, in the reliability test of the liquid crystal display device 1, thermal shock was applied to the liquid crystal display device 1. The thermal shock refers to the following phenomenon: when the liquid crystal display device 1 undergoes a rapid temperature change from a high temperature to a low temperature or from a low temperature to a high temperature, thermal stress is generated by impact. Thereby, the liquid crystal display device 1 expands or contracts.
In the present embodiment, the gap 33 between the backlight 20 and the liquid crystal display panel 10 is not sealed. This can prevent the liquid crystal display panel 10 from warping.
[1-3] Effect of embodiment 1
As described above in detail, in embodiment 1, the liquid crystal display device 1 includes: a liquid crystal display panel 10; a backlight 20 for emitting light toward the liquid crystal display panel 10; an adhesive member 31 having a quadrangular shape and having a light shielding property, which bonds the liquid crystal display panel 10 and the backlight 20 with a space therebetween; and a frame 30 that surrounds and fixes the liquid crystal display panel 10 and the backlight 20. The adhesive member 31 has a notch 32 recessed outward and crossing the boundary between the backlight 20 and the frame 30.
Therefore, according to embodiment 1, the gap 33 between the backlight 20 and the liquid crystal display panel 10 is not sealed. Therefore, when the liquid crystal display device 1 is placed in a depressurized environment (for example, a vacuum environment), the liquid crystal display panel 10 can be prevented from warping. Further, even in the case where thermal shock is applied to the liquid crystal display device 1, the liquid crystal display panel 10 can be prevented from warping.
This can suppress expansion or contraction of the liquid crystal display device 1. In addition, it is possible to suppress local peeling or breakage of a plurality of members constituting the liquid crystal display device 1. As a result, the quality of the liquid crystal display device 1 can be improved.
[2] Embodiment 2
Fig. 10 is a plan view of an adhesive member 31 according to embodiment 2 of the present invention. In fig. 10, the outer shape of the backlight 20 is shown by a dotted line.
The notch 32 extends in the Y direction and reaches the end of the adhesive member 31. As in embodiment 1, the cutout portion 32 crosses an end portion of the backlight 20 (corresponding to a boundary between the backlight 20 and the frame 30).
Even when notch 32 is formed as in embodiment 2, the same effects as those of embodiment 1 can be obtained.
Fig. 11 is a plan view of the adhesive member 31 of modification 1. The notch 32 extends in an oblique direction with respect to one side of the adhesive member 31. According to modification 1, it is possible to suppress the entry of foreign matter into the gap 33 through the notch 32.
Fig. 12 is a plan view of an adhesive member 31 according to modification 2.
