摘要： The application disclose an embedded capacitive touch display panel and an embedded capacitive touch display device, including: a first transparent substrate and a second substrate arranged opposite to each other, a grid-shaped metal conductive layer formed on the first transparent substrate, and a number of force touch detection electrodes independent of each other formed on the second substrate, wherein the embedded capacitive touch display panel further includes a color filter layer including at least red color resists, green color resists, and blue color resists, wherein the color resists in the same colors are arranged in respective color resist bars, and the color resist bars including green color resist resistance strips; and the grid-shaped metal conductive layer includes periodically arranged force touch fixed potential electrodes and floating electrodes, wherein the force touch fixed potential electrodes are separate from the floating electrodes with gaps being formed between them, and the gaps include first gap sections which are parallel to the color resist bars, and which do not overlap with the green color resist resistance strips. Since the green color resists contribute to display brightness far more than the color resists of the other colors, the first gap sections can be arranged so that they do not overlap with the green color resist resistance strips to thereby alleviate the problem of a visible pattern of the grid-shaped metal conductive layer so as to improve the display performance of the embedded capacitive touch display panel without degrading a touch effect.
