As shown in fig. 3 and 4, the liquid crystal display device includes: backlight unit 10, first liquid crystal cell 20 and second liquid crystal cell 30 all include display area and non-display area, and non-display area surrounds the display area, and liquid crystal display device still includes: an inter-cell adhesive layer 40, the inter-cell adhesive layer 40 being disposed between the first liquid crystal cell 20 and the second liquid crystal cell 30 and capable of bonding the first liquid crystal cell 20 and the second liquid crystal cell 30; the inter-case adhesive layer 40 includes a plurality of adhesive portions 41, and at least some of the adhesive portions 41 are disposed at intervals in the display area AA.
The backlight module 10 is disposed below (not light-emitting) the first liquid crystal cell 20 and the second liquid crystal cell 30, and is used as a backlight source to emit light for lighting the liquid crystal display. The backlight source in the backlight module 10 may include a Light Emitting Diode (LED), a Cold Cathode Fluorescent Lamp (CCFL), an electroluminescent sheet (EL), and/or an Organic electroluminescent sheet (OLED), for example.
The first liquid crystal cell 20 may be an LCD liquid crystal cell that plays a main role in a liquid crystal display, and is configured to adjust a twist angle, an arrangement direction, and the like of liquid crystal molecules under the effect of different voltages applied to the liquid crystal molecules, so that light emitted from the backlight module 10 can be emitted along different arrangement directions of the liquid crystal molecules, thereby exhibiting different light characteristics, and implementing brightness adjustment and different color display of the liquid crystal display.

Therefore, the embodiment of the utility model solves the problem of depth of field caused by nonuniform gap between the double cells easily caused by the adoption of the square glue, and the embodiment of the utility model improves the display effect of the liquid crystal display device. In addition, because the gap between the first liquid crystal cell 20 and the second liquid crystal cell 30 is uniform, compared with frame pasting by using a square glue, warping is not easy to occur, thereby being beneficial to avoiding the problem of fragment caused by warping. Compared with the mode of full lamination of optical cement in the prior art, the bonding parts 41 provided by the embodiment of the utility model are arranged at intervals. That is, by limiting the position where the adhesive portion 41 is provided, the liquid crystal display device according to the embodiment of the present invention can avoid the influence on the display. Therefore, the embodiment of the utility model solves the problem of Moire caused by adopting the full-lamination mode of the optical cement, and the embodiment of the utility model improves the display effect of the liquid crystal display device.

In addition, because the gap between the first liquid crystal cell 20 and the second liquid crystal cell 30 is uniform, compared with frame pasting by using a square glue, warping is not easy to occur, thereby being beneficial to avoiding the problem of fragment caused by warping. Compared with the mode of full lamination of optical cement in the prior art, the bonding parts 41 provided by the embodiment of the utility model are arranged at intervals. The embodiment of the utility model solves the problem of moire caused by adopting the full-lamination mode of the optical adhesive, and improves the display effect of the liquid crystal display device.

In an embodiment of the present invention, optionally, the bonding portions 41 are in the shape of dots, a certain interval exists between two adjacent bonding portions 41, and the two adjacent bonding portions are arranged in a dot matrix, and a little glue is applied to the positions of the dot bonding portions 41 to tightly bond the first liquid crystal cell 20 and the second liquid crystal cell 30.
Fig. 7 is a schematic structural diagram of a first liquid crystal cell in a liquid crystal display device according to an embodiment of the present invention, and fig. 8 is a schematic structural diagram of an array substrate in the first liquid crystal cell according to the embodiment of the present invention. The present embodiment details the specific structure of the first liquid crystal cell in each of the above embodiments, and further defines the location of the bonding portion based on the structure of the first liquid crystal cell. As shown in fig. 7 and 8, optionally, the first liquid crystal cell 20 includes an array substrate 22, a first liquid crystal layer 23, and a color filter substrate 24, which are stacked. The first liquid crystal cell 20 includes pixels 21 arranged in an array, and the pixels 21 are located in the display region; wherein a space exists between adjacent pixels 21 and at least a portion of the bonding portion is located within the space.
Specifically, the first liquid crystal cell 20 includes a plurality of pixels 21, and the pixels 21 are arranged in an array at certain intervals. In the interval between each pixel 21, at least part of the intervals are provided with bonding parts corresponding to the corresponding positions of the inter-cell adhesive layers, so that glue is dispensed at the positions of the bonding parts corresponding to the intervals of the pixels 21, the first liquid crystal cell 20 and the second liquid crystal cell can be tightly fixed, and the normal display of the pixels 21 is not influenced.
With continued reference to fig. 8, specifically, the array substrate 22 is provided with pixels 21 arranged in an array and a driving circuit connected to each pixel 21. The array substrate 22 has a scan line 221 and a data line 222, the scan line 221 extends along a first direction, the data line 222 extends along a second direction, and the first direction and the second direction are perpendicular to each other, so that the scan line 221 and the data line 222 are perpendicularly arranged in a crossing manner. One pixel 21 is provided in each of pixel regions where the scanning line 221 and the data line 222 intersect. Further, in each pixel region, a field effect transistor is provided. A control electrode of the field effect transistor is electrically connected to the scan line 221, one of a source electrode and a drain electrode is electrically connected to the pixel 21, and the other is electrically connected to the data line 222. When the scanning line 221 sequentially outputs an electric signal to the control electrode of each field effect transistor one by one to control the field effect transistors to be turned on, each pixel 21 is turned on one by one and an electric signal is output through the data line 222, so that the liquid crystal display device realizes a display function.
On the basis of the above embodiments, optionally, the array substrate 22 includes a scan line 221 extending along a first direction and a data line 222 extending along a second direction, the scan line 221 and the data line 222 are located in the space, and the first direction and the second direction intersect; the vertical projection of the bonding portion 41 on the array substrate 22 is located on the scan line 221 and/or the data line 222. The scanning lines 221 and the data lines 222 are usually made of metal, so that the scanning lines 221 and the data lines 222 are opaque, and the bonding portions are disposed on the scanning lines 221 and/or the data lines 222, so that the bonding portions can avoid influence on display.

Specifically, the color filter substrate 24 in the first liquid crystal cell includes a plurality of color resistors 241, and the color resistors 241 are color photoresist materials used in a liquid crystal display device. When light emitted by the backlight source is emitted through the twisting of the liquid crystal molecules, the light passes through the color resistor 241 arranged on the color film substrate 24, so that the color display of the liquid crystal display device is realized. The color film substrate 24 includes a plurality of color resistors 241 arranged in an array, and a black matrix 242 is disposed at an interval between adjacent color resistors 241 to prevent light leakage between the color resistors, improve the color display effect of the liquid crystal display device, and improve the color contrast of the liquid crystal display device. In order to prevent the glue for bonding the first liquid crystal cell and the second liquid crystal cell from being disposed in the display area to affect the display effect, the vertical projection position of the bonding portion 41 coated with the glue on the color film substrate 24 corresponds to the black matrix 242 disposed at the interval position between the adjacent color resistors 241, so as to prevent the color resistors 241 in the array arrangement in the display area from being shielded, and ensure the colorized display effect.
Fig. 10 is a schematic structural diagram of another liquid crystal display device according to an embodiment of the present invention. The present embodiment adds the technical features of the specific structure of the liquid crystal display device in the above-described embodiments.

The inter-cell adhesive layer 40 is located between the first liquid crystal cell 20 and the second liquid crystal cell 30, and is disposed on a side of the array substrate 22 in the first liquid crystal cell 20 away from the color film substrate 24. Therefore, the bonding portion 41 is closer to the array substrate 22, and the position of the bonding portion 41 is easier to operate with the structure in the array substrate as a reference for alignment, and the position of the bonding portion 41 corresponds to the scanning lines and/or the data lines crossing each other in the display region of the array substrate 22 of the first liquid crystal cell 20.
