Liquid crystal panel and active matrix substrate used therefor
First Claim
1. A liquid crystal panel, comprising:
- a pair of substrates;
a liquid crystal layer provided between the pair of substrates; and
a sealing member provided between the pair of substrates so as to surround the liquid crystal layer;
the liquid crystal panel including a plurality of pixels provided in a matrix in a region surrounded by the sealing member;
wherein;
each of the plurality of pixels includes;
an oxide semiconductor TFT provided in one substrate of the pair of substrates; and
a pixel electrode provided in the one substrate and connected with the oxide semiconductor TFT;
the each of the plurality of pixels is configured such that when the oxide semiconductor TFT is switched from an on-state to an off-state, a level of a voltage to be applied to the liquid crystal layer by use of the pixel electrode is shifted in a negative direction by a pull-in voltage Δ
Vd; and
a pull-in voltage Δ
Vd1 in a first pixel among the plurality of pixels is lower than a pull-in voltage Δ
Vd2 in a second pixel located farther from the sealing member than the first pixel.

Abstract
A liquid crystal panel (100) includes a pair of substrates (10, 30); a liquid crystal layer (40) provided between the pair of substrates; and a sealing member (42) provided so as to surround the liquid crystal layer. A plurality of pixels (P1, P2) are provided in a matrix in a region surrounded by the sealing member. Each of the plurality of pixels includes an oxide semiconductor TFT (5) provided in one substrate (10) of the pair of substrates; and a pixel electrode (19) provided in the one substrate and connected with the oxide semiconductor TFT. Each of the plurality of pixels is configured such that when the oxide semiconductor TFT is switched from an on-state to an off-state, a level of a voltage to be applied to the liquid crystal layer by use of the pixel electrode is shifted in a negative direction by a pull-in voltage ΔVd. A pull-in voltage ΔVd1 in a first pixel (P1) among the plurality of pixels is lower than a pull-in voltage ΔVd2 in a second pixel (P2) located farther from the sealing member than the first pixel.
