Abstract: A color filter layer is formed on a glass substrate of a counter substrate. A bank pattern is formed of the same material as a red color-filter portion, a green color filter portion and a blue color filter portion of the color filter layer at the outside of the color filter layer on the glass substrate in the same step. A light shielding material is coated in a bank between the bank pattern and the color filter layer to form a light shielding layer. The light shielding layer can be formed so as to be continuous with the peripheral edge of the color filter layer. The light shielding layer is less likely to overlap with the inside of a display frame portion of the liquid crystal panel, and the aperture ratio is less likely to be reduced. The number of manufacturing steps of the light shielding layer is reduced.

A first color filter layer is provided between each pixel electrode and a gate insulating film of the array substrate. The first color filter layer of each pixel has spectral characteristics corresponding to the second color filter layer that is provided in association with the reflective region of the pixel.

Abstract: In order to reduce an occurrence of a double image, to improve a contrast ratio in transmissive display, and to widen a viewing angle, a light diffusion layer for restricting the occurrence of the double image is placed between a viewing angle compensating plate and a reflective layer. With this configuration, though traveling directions of light emitted from a backlight placed on an outside of the reflective layer are changed in the light diffusion layer, the traveling directions are not changed in the viewing angle compensating plate and a liquid crystal layer once the light is made incident onto the viewing angle compensating plate, and the light travels straight in any of the vertical direction and slanting directions. Thus, the viewing angle compensating plate can exert an original function thereof to compensate a phase difference and can ensure a viewing angle widely.

Abstract: In forward direction pulse shift, by turning off a sixteenth transistor, a through-current is prevented from flowing between the fifth transistor and the seventh transistor. In backward direction pulse shift, by turning off the fifteenth transistor, a through-current is prevented from flowing between the fifth and sixth transistors. Thus, a potential variation in an output signal of a shift register between the forward direction pulse shift and the backward direction pulse shift is prevented.

Abstract: Dummy holes 36 are made for every one of display dot 5a, 5b and 5c at pixels 5 through interlayer film 33 up to gate electrode and scanning lines 11 before interlayer film 33 on glass substrate 3 is washed. When interlayer film 33 is washed, electric charges stored at semiconductor layer 21 are substantially the same in quantity as those stored at gate electrode and scanning lines 11 through dummy holes 36. Thus, electric potentials at gate electrode and scanning lines 11 are substantially equal in magnitude to those at semiconductor layer 21. This can suppress the occurrence of voltage differences imposed between gate electrode and scanning lines 11 and semiconductor layer 21.
