Abstract:
1. An active-matrix substrate comprising: a semiconductor layer; a thin-film transistor element including a first thin-film transistor, which has a source region, a channel region and a drain region that are included in the semiconductor layer, wherein the channel region is defined by overlap with a gate; a gate bus line; a source bus line; and a pixel electrode, wherein the source region of the first thin-film transistor includes a source contact portion, and wherein the semiconductor layer has a first gettering region adjacent to the source region of the first thin-film transistor, and wherein the semiconductor layer has a first end portion, a second end portion and an intermediate portion between the first and second end portions, and wherein the first end portion has a greater width than the intermediate portion, and wherein a part of the source region of the first thin-film transistor, including the source contact portion, and the first gettering region are located in the first end portion, and wherein the first gettering region is located in an outer periphery of the first end portion except an electrical charge path leading from the source contact portion to the channel region of the first thin-film transistor, and wherein the active-matrix substrate satisfies d2>d1≧d3 and d2+A1/2>d3+L
