Abstract: 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.

Abstract: A display device includes a first substrate provided with at least one color filter layer that transmits light of a certain wavelength, a second substrate that is disposed opposed to the first substrate; and a fill layer disposed between the first substrate and the second substrate. The first substrate is provided with a display region in which the at least one color filter layer is disposed and which displays an image and a peripheral region that is positioned out of the display region. Wettability of a surface of the at least one color filter layer of the peripheral region is equal to or less than wettability of a surface of the at least one color filter layer of the display region.
