Abstract: According to one embodiment, a display device includes a transparent semiconductor, a first insulating layer, a gate electrode, a second insulating layer, a source electrode, a third insulating layer, a transparent electrode which is in contact with the semiconductor in a second contact hole penetrating the first insulating layer, the second insulating layer and the third insulating layer, a fourth insulating layer, a color filter, and a pixel electrode electrically connected to the transparent electrode. The first insulating layer and the second insulating layer are silicon oxide layers. At least one of the third insulating layer and the fourth insulating layer is a silicon nitride layer.

Abstract: The present invention aims to detect breakage of a sieve in real-time and thus substantially reduce a cost increase of products caused by sieve breakage. The present invention also aims to reduce management cost of a sieve substantially. Multiple conductive bands 40 through 51 of a predetermined width, composed of multiple (for example, ten, in the structure shown in the figures) conductive weaving threads 24 and multiple (for example, ten) nonconductive weaving threads 23 and a certain number of nonconductive weaving threads 25, are formed in one area of the screen member 5. These conductive bands 40 through 51 of combined weave are formed parallel to the axial direction X at certain intervals D. Between each conductive band 40 through 51, nonconductive bands 52 through 62 plane-woven by using the nonconductive weaving threads 23 and the nonconductive weaving threads 25 are formed. A continuous conductive element 82 of a folded shape is formed, as shown in FIGS.
