The array substrate 11 and the color filter substrate 12 are arranged in a box-to-box manner, the color filter substrate 12 is arranged in the light emitting direction Y of the array substrate 11, and the color filter substrate 12 includes a first substrate 121, a black matrix layer 122, a color resist layer 123, and a first alignment layer 124.
The first substrate 121 is usually made of glass, or other materials, and is not limited herein, the black matrix layer 122 is formed on the first substrate 121, the color resist layer 123 is formed on the first substrate 121 and is spaced apart from the black matrix layer 122, and the color resist layer 123 includes a plurality of color resist blocks disposed in a plurality of sub-pixel regions in a one-to-one correspondence.
The black matrix layer 122 surrounds a plurality of sub-pixel regions distributed in an array on the first substrate 121, and the plurality of color resist blocks are disposed in the plurality of sub-pixel regions in a one-to-one correspondence. The color-resistant blocks in the three sub-pixel regions in each pixel region can be respectively a red color-resistant block (R), a blue color-resistant block (B) and a green color-resistant block (G), wherein the red color-resistant block only allows red light to pass, the blue color-resistant block only allows blue light to pass, and the green color-resistant block only allows green light to pass.
The black matrix layer 122 is made of a metal material or an organic material, and the black matrix layer 122 is opaque.
In one embodiment, the width of the black matrix layer 122 in the second display area 200 is smaller than that of the first display area 100, that is, in the second display area 200, the area blocking light from entering becomes narrow, the path of the external light 110 entering the electronic component 30 becomes wide, and the light transmittance of the display device in the second display area 200 is increased.
In one embodiment, the thickness of the color resist layer 123 in the second display area 200 is less than that in the first display area 100. Since the external light 110 needs to enter the electronic element 30 through the color resist layer 123 above the electronic element 30, the thickness of the color resist layer 123 in the second display region 200 is reduced, so that the path of the external light 110 entering the electronic element 30 is reduced, and the light transmittance of the display device in the second display region 200 is increased.
A first alignment layer 124 is disposed on a side of the color filter substrate 12 close to the first liquid crystal 13, and is used for aligning liquid crystal molecules of the first liquid crystal 13 in a specific direction.

In one embodiment, the thickness of the first alignment layer 124 in the second display region 200 is less than the thickness in the first display region 100. Since the external light 110 needs to enter the electronic device 30 through the first alignment layer 124 above the electronic device 30, the thickness of the first alignment layer 124 in the second display region 200 is reduced, so that the path of the external light 110 entering the electronic device 30 is reduced, and the light transmittance of the display device in the second display region 200 is increased.
Certainly, the film structure of the color filter substrate 12 is not limited thereto, and between the black matrix layer 122 and the first alignment layer 124, the color filter substrate 12 further includes other films, and the light transmittance of the display device in the second display area 200 may also be increased by thinning the other light-transmitting films.

Since the external light 110 needs to enter the electronic component 30 through the light shielding layer 112 above the electronic component 30, the through hole of the second alignment layer 113 in the second display region 200 is reduced, i.e., the path of the external light 110 entering the electronic component 30 is reduced, thereby increasing the light transmittance of the display device in the second display region 200.
A second alignment layer 113 for aligning liquid crystal molecules of the first liquid crystal 13 in a specific direction is disposed on a side of the array substrate 12 adjacent to the first liquid crystal 13.
The material of the second alignment layer 113 is usually polyimide (Po l y imi de, P I), and is mainly prepared by a printing method and an inkjet method, i.e., an alignment liquid is applied onto the substrate by a printing or inkjet method, and then the alignment liquid is solidified to form the second alignment layer 113.
In one embodiment, the thickness of the second alignment layer 113 in the second display region 200 is smaller than that in the first display region 100. Since the external light 110 needs to enter the electronic component 30 through the second alignment layer 113 above the electronic component 30, the thickness of the second alignment layer 113 in the second display region 200 is reduced, so that the path of the external light 110 entering the electronic component 30 is reduced, and the light transmittance of the display device in the second display region 200 is increased.
Of course, the film structure of the array substrate 11 is not limited thereto, and may further include other films, such as a buffer layer, an active layer, a gate insulating layer, a gate electrode, an interlayer insulating layer, a source electrode, a drain electrode, and a passivation layer (not shown) on the light-shielding layer 112.

The material of the gate insulating layer is typically silicon oxide, silicon nitride, or the like, and may be a single-layer or multi-layer structure. The gate electrode is positioned on the gate insulating layer, and may be a single or multi-layer structure including gold (Au), silver (Ag), copper (Cu), nickel (Ni), platinum (Pt), palladium (Pd), aluminum (Al), Molybdenum (MO), or chromium (Cr), or a single or multi-layer structure such as aluminum (Al): neodymium (Nd) alloy and Molybdenum (MO) alloy, tungsten (W) alloy.

The passivation layer is positioned on the source electrode and the drain electrode, and may be formed of an inorganic material such as silicon oxide or silicon nitride.
The film structure is not limited to this, and other structures, such as a bottom gate structure, may also be used.
The light transmittance of the display device in the second display region 200 can also be increased by thinning other light-transmitting film layers.
The external light 110 enters the electronic component 30, and needs to pass through all the film layers above the electronic component 30 to thin the film layers, so that the light transmittance of the display device in the second display area 200 is increased, the external light 110 can better enter the electronic component 30, and the display image quality of the display device is further enhanced.
It should be noted that only a part of the film layers may be modified, or all the film layers that can be thinned or widened may be modified, and those skilled in the art may design the film layers as needed to increase the light transmittance of the display device in the second display region 200.
When the electronic component 30 is turned on, the external light 110 enters the electronic component 30, and since the light transmittance of the display device in the second display area 200 is increased, the image captured by the electronic component 30 is clearer, and no hole needs to be dug in the area above the electronic component 30.
Meanwhile, the liquid crystal cell below the electronic component 30 is powered on, the liquid crystal molecules of the second liquid crystal 43 deflect to block the light 21 emitted by the backlight module 20 in the area from passing through, and the captured image of the electronic component 30 is displayed through the screen in the first display area 100. When the electronic component 30 is turned off, the liquid crystal cell below the electronic component 30 is not powered on, the liquid crystal molecules of the second liquid crystal 43 are at the original deflection angle, the light 21 emitted by the backlight module 20 is allowed to penetrate through the electronic component 30, and the display panel in the area above the electronic component 30 displays pictures, so that the display panel 10 can normally display when the electronic component 30 works and does not work.
