In this embodiment, the color film 430 includes a plurality of color resists 431. The color film layer 430 is disposed in a whole layer, the color resistor 431 is disposed in the second display area 402, and the color resistor 431 is not disposed in the first display area 401, as shown in fig. 2, 3 and 4. One sub-pixel in the second display area 402 corresponds to one color resistor 431 of the color film layer 430. The color resistors 431 may be spaced apart. The color resist 431 has low light transmittance, and when the color film layer 430 is formed, the color resist 431 material is subjected to patterning treatment, so that the color resist 431 positioned in the first display area 401 is removed, the light transmittance of the first display area 401 is increased, the light receiving flux of the sensor 300 is improved, and the working quality of the sensor 300 is improved.

In this embodiment, the self-luminescent layer 700 and the liquid crystal layer 420 in the display panel 400 are disposed on the same layer, specifically, refer to fig. 2, 3 and 4. The liquid crystal layer 420 of the first display area 401 is free of liquid crystal in the application, the self-luminous layer 700 is arranged in the space, the thickness is not increased, the space utilization rate is improved, the change of the thickness of the film layer is avoided, and meanwhile, the space is filled in the self-luminous layer 700, so that the collapse of the film layer is avoided.
In this embodiment, the self-luminescent layer 700 and the color film layer 430 in the display panel 400 are disposed on the same layer. The self-luminous layer 700 can be formed by printing or evaporation, and the difficulty of formation is reduced similar to the color resist 431 material of the color film layer 430.
In this embodiment, the self-luminous layer 700 includes a plurality of light-emitting units 710, and the light-emitting units 710 emit light of any one of red, green and blue colors, as shown in fig. 2 to 4. The light emitting units 710 may be disposed at intervals.

In this embodiment, the light emitting unit 710 includes a mini-LED or a micro-LED.
In this embodiment, in a direction from the first display area 401 to the second display area 402, the density of the light emitting units 710 is gradually increased, specifically referring to fig. 1 and fig. 3. When the sensor 300 is in a non-operating state, the first display area 401 is intended to normally display, and the display effect is more likely to decrease near the edge of the first opening 201, and the density of the light emitting units 710 is increased by adjusting the density of the light emitting units 710 at the edge corresponding to the first opening 201, so that the display image is more exquisite, and the technical problem of the decrease of the display effect is solved.
In this embodiment, the light emitting frequency of the light emitting unit 710 is the same as the frequency of the display frame of the second display area 402. When the sensor 300 is in a non-operating state, the first display area 401 is required to be displayed normally, and is required to be coordinated with the picture image of the second display area 402, and the light emitting frequency can be adjusted through algorithm optimization, so that the light emitting frequency is fused with the display picture of the second display area 402 around, and a real full-screen display function is achieved.
In this embodiment, a distance between two adjacent light emitting units 710 is greater than a distance between two adjacent sub-pixels in the second display area 402, specifically refer to fig. 2, 3, and 4.

It is also possible that the distance between the center points of two adjacent light-emitting units 710 is greater than the distance between two adjacent sub-pixel center stores. One sub-pixel in the second display area 402 corresponds to one color resistor 431 of the color film layer 430. When the sensor 300 is in the non-operating state, the main function of the first display area 401 is to additionally display the display screen of the second display area 441, and at the same time, the first display area can receive more external light, so that the received light flux of the sensor 300 is increased, and the operating quality of the sensor 300 is improved.
In this embodiment, the pixel density of the first display area 401 is greater than the pixel density of the second display area 402. Because the light-emitting unit 710 has a small volume, it can bear a higher density of pixels, which is beneficial to improving the fineness of display and improving the impression of users.
In this embodiment, the self-luminous layer 700 further includes a first light shielding unit 720 located between two adjacent light emitting units 710.

In this embodiment, the self-light emitting layer 700 further includes a cathode layer and an anode layer, and the light emitting unit 710 is located between the cathode layer and the anode layer. The cathode layer is located on a side close to the sensor 300.
In this embodiment, the array substrate includes a plurality of thin film transistor units, the array substrate is disposed in the second display area 402, the cathode layer includes a plurality of cathode units, one cathode unit corresponds to one light emitting unit 710, and the cathode unit is electrically connected to the thin film transistor units through a transparent connection line. When the sensor 300 is in an operating state, the light transmittance of the first display region 401 is further increased, the light flux received by the sensor 300 is increased, and the operating quality of the sensor 300 is increased.
In this embodiment, the density of the tft units close to the first display region 401 is greater than the density of the tft units far from the first display region 401, so that the connection lines of the cathode units are more suitably electrically connected to the tft units, and the cathode units at the holes are normally connected.

When the sensor 300 is not in operation, the first black shutter curtain 800 is closed, so as to avoid the influence of natural light or the influence of light emitted from the light emitting unit 710 on the sensor 300, thereby increasing the service life of the sensor 300.
In this embodiment, the liquid crystal display device 100 further includes a first light guide unit surrounding the first display region 401. The first light guide unit comprises a first light transmission component and a second black shutter curtain.

The first light-passing component is used for passing light of the backlight module 200 in the second display area 402 into the first display area 401, and the second black shutter curtain is used for passing or blocking light of the first light-passing component. The first light transmission component comprises a first opening and a first tube wall, and the first opening is connected with the light guide part of the backlight module 200. Secondly, when the sensor 300 is in a non-operating state, the second black shutter curtain is opened, so that light of the first light transmission component passes through, the first display area 401 displays normally, and white light guided through the first light transmission component supplements the brightness of the first display area 401. Secondly, when the sensor 300 is in the working state, the second black shutter curtain is closed, so that the light of the first light-passing component is blocked, the sensor 300 can correctly receive the light emitted to the liquid crystal display device 100, and the deviation of the light flux caused by the light of the backlight module 200 is reduced.
In this embodiment, the liquid crystal display device 100 further includes a transflective film between the display panel 400 and the sensor 300.
