An object of the present invention is to provide a filter that makes it possible to suppress the initial pressure loss and, also, to reduce the rising rate of the pressure loss that increases as particulates accumulate; therefore, the pressure loss at the time when a prescribed amount of particulates have been collected becomes lower, and the pressure loss from the viewpoint of the period up to the recovery as a whole also becomes lower. The present invention provides a filter, which is a column shaped filter having a honeycomb structure, including a number of through holes that are placed in parallel with one another in the length direction with wall portion interposed therebetween, wherein the through holes are constituted by two types of through holes, that is, large-capacity through holes having a relatively larger cross-sectional area in the cross section perpendicular to the length direction and small-capacity through holes having a relatively smaller cross-sectional area in the cross section, with the numbers of the two types of through holes being substantially set to the same, the large-capacity through holes are sealed at one end of the filter, while the small-capacity through holes are sealed at the other end of the filter, and supposing that the ratio (a / b) of the total (a) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent large-capacity through hole in the cross section perpendicular to the length direction and the total (b) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent small-capacity through hole in the cross section perpendicular to the length direction is defined as a and that the ratio (A / B) of the area (A) of the cross section of the large-capacity through hole and the area (B) of the cross section of the small-capacity through hole is defined as β, α and β satisfy the relationship represented by the following formula (1): β≧(20 / 9) α2+1 (where 0<α≦1.5 and 1<β≧6)  (1).

The scanning lines extend in the first direction and corresponding to the sub-pixels of the rows respectively. Each data line includes a plurality of first data segments and second data segments connected alternately. The first data segment extends along a second direction and partially overlaps the scanning line in a vertical direction. Each second data segment is disposed on one side of the scanning line, and at least a portion of the second data segments extends along a third direction different from the first and second directions.

An image sensor, for example for incorporation within an active matrix display, comprises an array of sensor elements 10. Each sensor element (10) comprise an amplifying transistor (M1) whose gate is connected to an integrating node (11). The integrating node (11) is connected to one plate of an integrating capacitor (C1) and to one electrode of a photodiode (D1), whose other electrode is connected to a resetting line (RST). The sensor element (10) performs a repeating sensing cycle comprising a resetting phase, an integrating phase and a reading phase. During the resetting phase, the resetting line (RST) receives a voltage which forward-biases the photodiode (D1) so as to charge the integrating node (11) to a predetermined voltage. The resetting line (RST) is then returned to a voltage for reverse-biasing the photodiode (D1) so that the integrating and reading phases may be performed.
