Abstract: A loop antenna unit including two loop antennas having a same number of turns and different winding directions, the two loop antennas being positioned in line symmetry and not superposed on each other in a plan view. Each of the two loop antennas includes a loop conductive line wound continuously in one direction with n turns, where n is an integer of 3 or more, forming loops from a start point to an end point on the outermost loop or the innermost loop, the loop conductive line being bent in a transitional region in a direction from an outer loop toward an inner loop such that the loops have bent portions positioned side by side from an outermost first loop to an (n−1)th loop in the transitional region, and a jumper wire positioned on the insulating layer to cross the transitional region in a plan view.

Abstract: A color filter substrate for use in a fringe-field switching mode liquid crystal display wherein the color filter substrate and an array substrate provided with a comb-shaped pixel electrode having an electrode width of 10 μm or less are arranged facing each other with a liquid crystal layer interposed therebetween. The color filter substrate comprises a transparent substrate, a black matrix provided on the transparent substrate, includes an organic pigment as a main coloring agent, color pixels having a relative dielectric constant of 2.9 or more but 4.4 or less, and a transparent resin layer provided on the color pixels. The relative dielectric constant of each of the color pixels falls within ±0.3 of an average relative dielectric constant of the color pixels.
