A display substrate, a display panel and a display device are disclosed. The display substrate includes: a base substrate (1), and a color film structure (2) and a transparent conductive oxide film layer (3) subsequently laminated on the base substrate (1). The color film structure (2) includes a plurality of color filter units arranged in a matrix and having different colors; at least one color of the color filter units in the color film structure (2) includes at least two layers of laminated color filter films, refractive indices of the color filter films gradually increase in a direction from the base substrate (1) towards the transparent conductive oxide film layer (3), and one layer of the color filter films adjacent to the base substrate (1) has refractive index larger than that of the base substrate (1), one layer of the color filter films adjacent to the transparent conductive oxide film layer (3) has refractive index less than that of the transparent conductive oxide film layer (3). The display substrate reduces the loss of light transmitted in the display panel, and thus the display brightness of the display device is increased.

A liquid crystal display device includes: a display unit having a display substrate, an array substrate and a liquid crystal layer, and a control unit. The display substrate is composed of light absorbing resin layer patterns containing a black material, copper alloy film patterns, a transparent resin layer and transparent electrode patterns laminated in this order. The array substrate includes a metal wiring, pixel electrodes, thin film transistors and an insulation layer. The light absorbing resin layer patterns and the copper alloy film patterns are formed in an identical pattern being overlapped with each other. The copper alloy film patterns are arranged in a first direction to be insulated from each other. The transparent electrode patterns are arranged in a second direction to be insulated from each other. The control unit drives liquid crystals and detects a change in an electrostatic capacitance in a time sharing manner.

There are provided a transparent conductive film, as well as a heater, a touch panel, a solar battery, an organic EL device, a liquid crystal device, and an electronic paper that are provided with the transparent conductive film, the transparent conductive film being capable of easing a decline in optical transmittance when graphene is laminated, and of achieving optical transmittance higher than an upper limit of optical transmittance of a single layer of graphene. The transparent conductive film includes a single-layered conductive graphene sheet. The single-layered conductive graphene sheet includes a first region and a second region, the first region being configured of graphene, and the second region being surrounded by the first region and having optical transmittance that is higher than optical transmittance of the first region.

The conductive film includes a substrate, a first conductive layer formed on the substrate, and a patterned second conductive layer formed on the first conductive layer. Here, oxide layers are formed on top and side surfaces of the second conductive layer. The conductive film may prevent defects of the conductive layer caused by rapid oxidation or damage to the substrate, and increase emission uniformity.

There is provided a transparent conductive film having a transparent conductor layer with a high level of pen input durability and high-temperature, high-humidity reliability. The transparent conductive film of the present invention is a transparent conductive film, comprising:

a transparent film substrate; a transparent conductor layer that is provided on one side of the transparent film substrate and has a thickness d of 15 nm to 35 nm and an average surface roughness Ra of 0.37 nm to 1 nm; and at least a single layer of an undercoat layer interposed between the transparent film substrate and the transparent conductor layer.
