Patent number: 10845651Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.Type: GrantFiled: March 23, 2020Date of Patent: November 24, 2020Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Takahiro Ochiai, Tohru Sasaki, Tetsuya Nagata
