  • Patent number: 10957713
    Abstract: The present invention teaches a LTPS TFT substrate and its manufacturing method. The manufacturing method, after forming vias using the photoresist layer on the ILD layer and the gate insulation layer above the source/drain contact regions, and before peeling the photoresist layer, forms conductive layers in the vias by depositing conductive material in the vias. The source/drain electrodes contact the conductive layers in the vias and therefore are conducted to the source/drain contact regions, thereby effectively resolving the problem of contact impedance being too high between the source/drain electrodes and the source/drain contact regions from the existing re-etch LDD technique. Then, through the re-etch LDD technique, the present invention is able to omit a mask process without sacrificing product characteristics.

  • Patent number: 10861401
    Abstract: To provide a liquid crystal display device which can perform image display in both modes: a reflective mode where external light is used as an illumination light source; and a transmissive mode where a backlight is used. In one pixel, a region where incident light through a liquid crystal layer is reflected to perform display (reflective region) and a region through which light from the backlight passes to perform display (transmissive region) are provided, and image display can be performed in both modes: the reflective mode where external light is used as an illumination light source; and the transmissive mode where the backlight is used as an illumination light source. In addition, two transistors connected to respective pixel electrode layers are provided in one pixel, and the two transistors are separately operated, whereby display of the reflective region and display of the transmissive region can be controlled independently.

  • Patent number: 10852589
    Abstract: The present invention prevents the shaving of an alignment film caused by a columnar spacer in a liquid crystal display device of an IPS method using photo-alignment. A plinth higher than a pixel electrode is formed at a part where a columnar spacer formed over a counter substrate touches a TFT substrate. When an alignment film of a double-layered structure is applied over the pixel electrode and the plinth, the thickness of the alignment film over the plinth reduces by a leveling effect. When photo-alignment is applied in the state, a photodegraded upper alignment film over the plinth disappears and a lower alignment film having a high mechanical strength remains. As a result, it is possible to prevent the shaving of the alignment film.
