1. A liquid crystal display panel comprising:
a first substrate;
a second substrate facing the first substrate;
a liquid crystal between the first substrate and the second substrate;
pixels each including a transmissive display portion and a reflective display region;
reflectors disposed between the second substrate and the liquid crystal;
a first color filter arranged on an observation side with respect to the reflectors, the first color filter transmitting light with a wavelength corresponding to a first color, the first color filter including a first deep-color portion and a first light-color portion having an optical density lower than an optical density of the first deep-color portion, the first deep-color portion being located in the transmissive display portion of the corresponding pixel, the first light-color portion being located in the reflective display portion of the corresponding pixel;
a second color filter arranged on the observation side with respect to the reflectors, the second color filter transmitting light with a wavelength corresponding to a second color, the second color filter including a second deep-color portion and a second light-color portion having an optical density lower than an optical density of the second deep-color portion, the second deep-color portion being located in the transmissive display portion of the corresponding pixel, the second light-color portion being located in the reflective display portion of the corresponding pixel; and
a light-shielding layer formed of a laminate structure including at least the first deep-color portion, the first deep-color portion included in the light shielding layer being thinner than the first deep-color portion located in the transmissive display portion of the corresponding pixel.
