The embodiment of the application provides a display panel and a display device, wherein the display panel can be a display panel in a display device such as a mobile phone, a computer, a television, a multimedia display device and the like, and is not limited herein.

In a first aspect, embodiments of the present application provide a display panel 100. Referring to fig. 3, the display panel 100 has a display area 1a and a frame area 1b disposed at the periphery of the display area 1a, and the display panel 100 includes an upper substrate 1, a lower substrate 2, a color resist layer 3 and a spacer layer 4 disposed opposite to each other; the lower substrate 2 is provided with a thin film transistor 21 in the display area 1 a; the color resist layer 3 is disposed on the lower substrate 2 and includes a first color resist 31 and a second color resist 32, the first color resist 31 is disposed on the display area 1a and on the thin film transistor 21, and the second color resist 32 is disposed on the frame area 1b and spaced apart from the first color resist 31 to form a gap 33; the spacer layer 4 includes a first black matrix isolation portion 41 and a second black matrix isolation portion 42, the first black matrix isolation portion 41 is located between the display area 1a and the first color resistor 31 and the upper substrate 1, the second black matrix isolation portion 42 is located above the second color resistor 32 in the frame area 1b, and one side edge of the second black matrix isolation portion 42 extends toward the display area 1a to end in the gap 33, so that an upper surface 421 of the second black matrix isolation portion 42 sinks to form a transition surface 422 at a position corresponding to the gap 33.

As can be understood, referring to fig. 1, in the conventional narrow bezel product, the outer side of the display panel 100' is only provided with a middle frame 7', the lower substrate 2' near one side of the backlight module needs to be adhered and fixed to the middle frame 7' by a black tape 73', a lower polarizer 9' is attached to one side of the lower substrate 2' facing the backlight module, a gap exists between the lower polarizer 9' and the black tape 73', some light emitted by the backlight module can pass through the gap, among the light entering the bezel area 1b ' from the gap, 8% of the light with a wavelength band of 410nm can pass through the BPS material 42' arranged in the bezel area 1b ', so that some blue light can pass through the upper polarizer 8' above the upper substrate 1', thereby causing light leakage in the bezel area 1b '. In order to solve the problem of light leakage in the frame area 1b ', referring to fig. 2, it is proposed in the prior art that a color resistor 32' is disposed below the BPS 42 'in the frame area 1b', and the light leakage can be filtered by jointly shielding the color resistor 32 'and the BPS 42'; however, the arrangement of the color resistor 32 'can raise the topography of the BPS 42' of the frame area 1b ', the side edge of the BPS 42' facing the display area 1a 'forms a retaining wall, and when PI liquid is coated on the BPS 42' in the subsequent process, the PI liquid can flow back and accumulate on the side edge of the BPS 42', so that the pretilt angle of the liquid crystal is larger at the place, light leakage occurs in the dark state, and the mura problem around the display panel 100' occurs.

In the display panel 100 provided in the present application, referring to fig. 3, in the display area 1a, a first color resistor 31 and a first black matrix isolation portion 41 on the lower substrate 2 are used to jointly shade light between adjacent pixels in the display area 1a, and at the same time, the first black matrix isolation portion 41 supports the upper substrate 1 to maintain a space between the upper substrate 1 and the lower substrate 2; in the frame area 1b, the second color resistor 32 and the second black matrix isolation portion 42 on the lower substrate 2 are used for jointly shielding the frame area 1b, so as to prevent the display panel 100 from light leakage in the frame area 1 b; meanwhile, the distance between the second color resistor 32 and the first color resistor 31 is increased, a gap 33 is formed between the second color resistor 32 and the first color resistor 31, when the second black matrix isolation portion 42 is manufactured on the second color resistor 32, the side edge of the second black matrix isolation portion 42, which faces the display area 1a, extends to be stopped in the gap 33, the upper surface 421 of the second black matrix isolation portion 42 is sunk at the position corresponding to the gap 33 to form the transition surface 422, and the topography of the transition surface 422 relative to the upper surface 421 of the second black matrix isolation portion 42 is lower, so that the topography of the second black matrix isolation portion 42, which is close to the side edge of the display area 1a, is reduced, PI liquid is not accumulated, and the alignment layer is uniformly distributed, so that the pretilt angle of the liquid crystal is similar to each place, and the problem of the periphery mura of the display panel 100 in the dark state is solved.

In an embodiment, the display panel 100 further includes a first alignment layer 51 and a second alignment layer 52; the first alignment layer 51 is disposed on a side of the upper substrate 1 facing the lower substrate 2; the second alignment layer 52 is disposed on the upper surface 421 of the second black matrix isolation portion 42, the second alignment layer 52 is located in the frame area 1b, and one side of the first alignment layer 51 extends to the display area 1a and ends in the first black matrix isolation portion 41; it can be understood that the initial alignment of the liquid crystal molecules is a key factor of the display panel 100, has a great influence on the photoelectric performance of the display panel 100, and the alignment layer is a key factor for obtaining stable and uniform alignment of the liquid crystal molecules; by providing the first alignment layer 51 and the second alignment layer 52, the liquid crystal molecules of the display panel 100 have uniform and stable pretilt angles, so that the arrangement of the liquid crystal molecules is stable and uniform; meanwhile, the upper surface 421 of the second black matrix isolation portion 42 is sunk at the position corresponding to the gap 33 to form the transition surface 422, so as to reduce the topography of the second black matrix isolation portion 42 near the side of the display area 1a, the second alignment layer 52 is formed on the upper surface 421 of the second black matrix isolation portion 42, and extends to the display area 1a via the transition surface 422 and ends at the first black matrix isolation portion 41, so that PI liquid flow of the second alignment layer 52 is uniform, accumulation is not generated at the side of the second black matrix isolation portion 42, and thus partial area of liquid crystal molecule pretilt angle is prevented from being large, light leakage and peripheral mura problems of the display panel 100 in a dark state are avoided.

In the present application, the first color resistor 31 includes a red color resistor, a green color resistor, and a blue color resistor; in the display area 1a of the lower substrate 2, the first color resistor 31 is set as red, green and blue color resistors for forming red, blue and green color lights emitted from the display panel 100.

In the present application, the second color resist 32 is set as a green color resist or a red color resist; it is known that 8% of the light having a wavelength of 410nm passes through the second black matrix spacers 42 disposed in the frame area 1b, so that part of the blue light passes through the upper substrate 1, thereby causing the light leakage in the frame area 1b, and the light leakage in the frame area 1b is blue; by setting the second color resist 32 to be green or red, blue light can be completely filtered, and the effect of preventing light leakage in the frame area 1b can be further improved.

It should be noted that the above two technical features may be alternatively or simultaneously set, and specifically, in an embodiment, the above two technical features are simultaneously set.

It can be understood that, the thickness of the second black matrix isolation portion 42 is generally 1.3 μm, when the width of the gap 33 between the second color resistor 32 and the first color resistor 31 is smaller, the gap 33 will be filled by the second black matrix isolation portion 42 when the second black matrix isolation portion 42 is manufactured, and the effect of reducing the side topography of the second black matrix isolation portion 42 cannot be achieved; in an embodiment, referring to fig. 4, the width of the gap 33 is set to be 100 μm-500 μm, so that the distance between the first color resistor 31 and the second color resistor 32 is wider, and after the side edge of the second black matrix isolation portion 42 extends into the gap 33, the upper surface 421 of the second black matrix isolation portion 42 is significantly sunk at the position corresponding to the gap 33, so as to form the transition surface 422, thereby reducing the topography of the second black matrix isolation portion 42 near the side edge of the display area 1a, and solving the problem of PI liquid accumulation at the side edge.

Similarly, when the level difference between the transition surface 422 and the upper surface 421 of the second black matrix spacer 42 is too small, the position of the transition surface 422 is not actually lowered significantly, the side topography of the second black matrix spacer 42 is still high, there is still a risk of PI liquid accumulating on the side, and in an embodiment, referring further to fig. 4, the level difference between the transition surface 422 and the upper surface 421 of the second black matrix spacer 42 is set to H ₁ Wherein H is more than or equal to 0.6 mu m ₁ At this time, the transition surface 422 is significantly lowered compared to the upper surface 421 of the second black matrix spacer 42, and the side topography of the second black matrix spacer 42 is significantly lowered, thereby eliminating the risk of PI liquid accumulation on the side.

In an embodiment, the lower substrate 2 further comprises a lower substrate; the thin film transistor 21 is disposed over the lower substrate; with further reference to fig. 3, the lower substrate 2 further includes a polymer layer 22, the polymer layer 22 is disposed on the lower substrate and covers the thin film transistor 21 and the color resist layer 3, and a portion of the polymer layer 22 is disposed in the gap 33 to form a groove on a surface of a side thereof away from the substrate; wherein the spacer layer 4 is disposed on the polymer layer 22, and one side of the second black matrix spacer 42 extends toward the display area 1a and ends in the groove; the transition surface 422 corresponds to the groove location.

In this embodiment, the polymer layer 22 is provided to separate the color resist layer 3 and the spacer layer 4, when the polymer layer 22 is fabricated on the color resist layer 3, the material flows into the gap 33, so that when the second black matrix spacer portion 42 is fabricated on the polymer layer 22, the second black matrix spacer portion 42 extends into the groove toward the side of the display layer, and thus the transition surface 422 is formed on the upper surface 421, that is, from the frame region 1b to the direction of the display region 1a, the upper surface 421 of the second black matrix spacer portion 42, the transition surface 422 and the polymer layer 22 are arranged in a stepwise manner, and descend layer by layer, when the second alignment layer 52 is fabricated on the spacer layer 4, the second alignment layer 52 is fabricated along the upper surface 421 of the second black matrix spacer portion 42, and when the second black matrix spacer portion 421 is fabricated on the side of the second black matrix spacer portion 42, the second alignment layer 421 is not aligned along the upper surface 421 of the second black matrix spacer portion 22, so that the second black matrix spacer portion 52 can be stacked on the upper surface 421 and the side of the second black matrix spacer portion 52, and thus the second black matrix spacer portion 52 can be stacked on the upper surface of the second black matrix spacer portion 52, thereby achieving a near-black matrix spacer portion 52.

The specific material of the polymer layer 22 is not limited in this application, and in one embodiment, the material of the polymer layer 22 includes PFA (Polyfluoroalkoxy, tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer).

In this application, referring further to fig. 4, the transition surface 422 is spaced from the upper surface 421 of the polymer layer 22 by a distance H ₂ Wherein H is more than or equal to 0.9 mu m ₂ Less than or equal to 1.1 mu m; so configured, the transition surface 422 is significantly submerged compared to the upper surface 421 of the second black matrix spacer 42, and the side topography of the second black matrix spacer 42 is significantly lowered, thereby eliminating the risk of PI liquid accumulation on the side.

In this application, referring further to fig. 4, the transition surface 422 is spaced from the upper surface 421 of the polymer layer 22 by a distance H ₃ Wherein H is 3.2 μm ₃ ≤3.4μm。
