Touch screen panel

摘要

A touch screen panel includes a transparent substrate; a plurality of first sensing patterns at a first side of the transparent substrate and coupled to each other along a first direction; a plurality of second sensing patterns at the first side of the transparent substrate and coupled to each other along a second direction, the second sensing patterns being alternately arranged with the first sensing patterns not to overlap with the first sensing patterns; and a phase difference compensating layer at the first side of the transparent substrate and adapted to compensate for a birefringence phase difference of a liquid crystal layer in a liquid crystal display panel at a second side of the transparent substrate.

1. A touch screen panel comprising:
a transparent substrate; a plurality of first sensing patterns at a first side of the transparent substrate and coupled to each other along a first direction; a plurality of second sensing patterns at the first side of the transparent substrate and coupled to each other along a second direction, the second sensing patterns being alternately arranged with the first sensing patterns not to overlap with the first sensing patterns; an insulating layer on the second sensing patterns and spaced from the first sensing patterns; a phase difference compensating layer comprising a transparent liquid crystal material at the first side of the transparent substrate and controlled to compensate for a birefringence phase difference of a liquid crystal layer in a liquid crystal display panel at a second side of the transparent substrate; a color filter layer between the phase difference compensating layer and the liquid crystal layer, the color filter layer comprising a red layer, a green layer, and a blue layer; a transparent ground electrode on the second side of the transparent substrate; and an insulating film on the second side of the transparent substrate and covering the transparent ground electrode, wherein at least some of the plurality of second sensing patterns are in the phase difference compensating layer, and wherein the phase difference compensating layer is formed using a liquid crystal injection or coating method.
