  • Patent number: 10317586
    Abstract: Embodiments of the present invention relates to a thin film transistor and a method for manufacturing the same, a display substrate and a display device. The thin film transistor comprises an active layer, a source electrode, a drain electrode and an ohmic contact layer, wherein the ohmic contact layer is disposed between the active layer and the source electrode and/or between the active layer and the drain electrode to improve an ohmic contact property of the active layer with the source electrode and/or the drain electrode. The present invention solves the problem of poor ohmic contact effect between the active layer and the source and drain electrodes in the existing thin film transistor, thereby improving the ohmic contact property of the active layer with the source and drain electrodes and meanwhile improving display effect of images of a display.

  • Patent number: 9760001
    Abstract: A manufacturing method of a color filter substrate includes: depositing a photoresist layer on a substrate, patterning the photoresist layer through exposure and development and executing an UV curing; or forming an overcoat whose material is a light-cured material on a substrate, conducting an UV irradiation on the substrate from front and back sides of the substrate, respectively; or, depositing a black matrix photoresist, a red photoresist, a green photoresist and a blue photoresist on a substrate, respectively, and forming corresponding patterns respectively through exposure and development and executing an UV curing. By the technical solution, the line-width of a BM can be restrained from broadening, and the curing time can be shortened, thereby raising the production efficiency.
