The orthographic projection of the thin film transistor 103 on the substrate 101 is within the orthographic projection of the light shielding layer 107 on the substrate 101.
In this embodiment, the substrate 101 may be one of a glass substrate, a quartz substrate, a resin substrate, and the like. The substrate 101 may also be a flexible substrate, and a material of the flexible substrate may include polyimide.
By forming the light-shielding layer 107 on the thin film transistor 103 and covering the light-shielding layer 107 on the thin film transistor 103, the problem of on-current and off-current changes of the TFT device caused by reflected light or stray light is effectively solved.
The technical solution of the present application will now be described with reference to specific embodiments.
Example one
Referring to fig. 1, the light-shielding layer 107 at least includes a first light-shielding layer 108.
In this embodiment, the first light-shielding layer 108 is made of one of a light-reflecting material and a black light-absorbing material.

In this embodiment, the light-shielding layer 107 is formed on the thin film transistor 103, and the light-shielding layer 107 covers the thin film transistor 103, so that the problem of on-current and off-current variation of the TFT device caused by reflected light or stray light is effectively solved.
Example two
Referring to fig. 2 to 3 and fig. 10, the present embodiment is the same as or similar to the first embodiment, except that:
the light-shielding layer 107 includes at least a first light-shielding layer 108 and a second light-shielding layer 109.
Referring to fig. 2, the second light-shielding layer 109 may be disposed on the first light-shielding layer 108. Referring to fig. 3, the first light-shielding layer 108 may be disposed on the second light-shielding layer 109. The position between the first light-shielding layer 108 and the second light-shielding layer 109 is not particularly limited in the present application.
In this embodiment, the first light shielding layer 108 may be a color-resistant material, and the second light shielding layer 109 may be a color-resistant material having a different color from the first light shielding layer 108.
In this embodiment, the first light shielding layer 108 may be a color-resistant material, and the second light shielding layer 109 may be one of a light-reflecting material and a black light-absorbing material.

In this embodiment, the color-resisting material may be one of a red color-resisting material, a green color-resisting material, or a blue color-resisting material.
In this embodiment, when the first light shielding layer 108 and/or the second light shielding layer 109 are made of a color resist material, the color may be different from the color of the first color resist 105 and/or the second color resist 106.
In this embodiment, when the first light-shielding layer 108 and the second light-shielding layer 109 are both made of color-resist materials, the wavelength range of light included in the superposition of the wavelength range of light absorbed by the red color resist and the wavelength range of light absorbed by the blue color resist is the largest, and the wavelength range of light included in the superposition of the wavelength range of light absorbed by the green color resist and the wavelength range of light absorbed by the blue color resist is the smallest, in consideration of the difference between the color-resist light-transmitting wavelength bands of different colors. Therefore, the light shielding efficiency of the two-layer color resistance stack is as follows from high to low: red and blue color resists, red and green color resists, and green and blue color resists.
In this embodiment, by providing the light-shielding layer 107 with a double-layer structure, the light-shielding layer 107 may be discontinuous from the first color resist 105 and/or the second color resist 106, so that a black light-absorbing material or a light-reflecting material may be selected, thereby increasing the variety of material choices of the light-shielding layer 107; and because the light-shielding layer 107 may be discontinuous with the first color resistance and/or the second color resistance 106, when the first light-shielding layer 108 and the second light-shielding layer 109 are both color resistance materials, an optimal color resistance combination, that is, a combination of a red color resistance and a blue color resistance, may be selected; the light shielding layer 107 with the double-layer structure plays a role in shielding the combination of the color-resisting material, the black light-absorbing material and the light-reflecting material, and effectively solves the problem of on-current and off-current changes of the TFT device caused by reflected light or stray light.

In this embodiment, when the second light shielding layer 109 is continuous with the second color resist 106, the second light shielding layer 109 and the second color resist 106 may be formed in the same process.
In this embodiment, by providing the light-shielding layer 107 having a double-layer structure, the first light-shielding layer 108 can be formed in the same process and material as the first color resist 105, and the second light-shielding layer 109 can be formed in the same process and material as the second color resist 106, thereby simplifying the process steps; the light shielding layer 107 with the double-layer structure plays a role in shielding the combination of a color-resisting material, a black light-absorbing material and a light-reflecting material, and effectively solves the problems of on-current and off-current change of the TFT device caused by reflected light or stray light.
Example four

In this embodiment, whether the first light shielding layer 108 is continuous with the first color resist 105 and whether the second light shielding layer 109 is continuous with the second color resist 106 are not limited.
In this embodiment, when the first light shielding layer 108 is a color resist material, the first light shielding layer 108 and the first color resist 105 can be formed in the same process.
In this embodiment, when the second light shielding layer 109 is a color resist material, the second light shielding layer 109 and the first color resist 105 can be formed in the same process.
In this embodiment, by providing the light-shielding layer 107 with a three-layer structure, when the first light-shielding layer 108, the second light-shielding layer 109, and the third light-shielding layer 110 are all made of color-resistant materials, the three light-shielding layers adopt color-resistant materials with different colors, and the light-shielding layer 107 can absorb reflected light or stray light more completely; when the first light shielding layer 108 is made of color-resistant material, the first light shielding layer 108 can be formed by the same process and the same material as the first color resist 105, and when the second light shielding layer 109 is made of color-resistant material, the second light shielding layer 109 can be formed by the same process and the same material as the second color resist 106, so that the process steps are simplified; the light shielding layer 107 with the three-layer structure plays a role in shielding the combination of the color-resisting material, the black light-absorbing material and the light-reflecting material, and effectively solves the problems of on-current and off-current change of the TFT device caused by reflected light or stray light.
Referring to fig. 8, in the first to third embodiments, the first embodiment is taken as an example:
the light-shielding layer 107 includes a first portion 111 located right above the thin film transistor 103 and second portions 112 located at both sides of the thin film transistor 103. The first portion 111 is parallel to the substrate 101, and a side of the second portion 112 remote from the first portion 111 is disposed close to the substrate 101.

Referring to fig. 9, in the second embodiment and the third embodiment, the second embodiment is taken as an example:
when the first light-shielding layer 108 and the second light-shielding layer 109 are made of color-resist materials, in consideration of the difference in wavelength range of light absorbed by color resists of different colors, in order to avoid that the remaining light cannot be completely absorbed by the other light-shielding layer after the light passes through one light-shielding layer, the ratio of the thicknesses of the first light-shielding layer 108 and the second light-shielding layer 109 in the first portion 111 is 0.8 to 1.2.
In this embodiment, the ratio of the thicknesses of the first light-shielding layer 108 and the second light-shielding layer 109 in the first portion 111 is 1.
