Abstract: A color filter substrate includes first and second color filters exhibiting different colors and a light blocking portion. The light blocking portion includes a first transmissive film, a first reflective film on an upper layer side of the first transmissive film, a second transmissive film on an upper layer side of the first reflective film, and a second reflective film on an upper layer side of the second transmissive film and being thicker than the first reflective film. The first transmissive film includes a first bottom surface and a first side surface being inclined at a first angle with respect to the first bottom surface. The second reflective film includes a second bottom surface extending parallel to the first bottom surface and a second side surface being inclined at a second angle with respect to the second bottom surface. The first angle and the second angle are acute angles.

Abstract: Provided are a liquid crystal panel which has good visibility and in which a decrease in the display quality is sufficiently suppressed, and a head mounted display and a liquid crystal display device using the same. The liquid crystal panel includes a liquid crystal layer, a spacer, and a light-shielding section between a first substrate a second substrate facing the first substrate. The light-shielding section includes column-direction light-shielding sections arranged in a column direction and shielding parts between the pixels aligned in a row direction from light, and row-direction light-shielding sections arranged in the row direction and shielding parts between the pixels aligned in the column direction from light. The row-direction light-shielding sections include one that includes a first light-shielding section including an arrangement region of the spacer and a second light-shielding section adjacent to the first light-shielding section in the column direction.

Abstract: The present invention provides a liquid crystal panel capable of suppressing an occurrence of oblique color mixing, having excellent transmittance, and meeting the need for higher definition. The present invention also provides a liquid crystal display device and a head mounted display device including the liquid crystal panel. The liquid crystal panel includes: a first substrate having a plurality of pixels arranged in a matrix; a second substrate facing the first substrate; and a liquid crystal layer located between the first substrate and the second substrate. The first substrate includes a support substrate, a plurality of source lines, a plurality of gate lines, and a plurality of switching elements. Each of the pixels is defined by two gate lines adjacent to each other and two source lines adjacent to each other, and includes a pixel electrode and a color filter layer.

Abstract: A display device includes a first color filter, a second color filter, a first pixel electrode, a second pixel electrode, a common electrode, an insulating film, and a light blocking part that is disposed at a boundary between the first color filter and the second color filter. The light blocking part includes a light blocking film, a first transmission film disposed on the upper layer side of the light blocking film, and a reflection/transmission film disposed on the upper layer side of the first transmission film, the light blocking film has a light transmittance lower than light transmittances of the first transmission film and the reflection/transmission film, the first transmission film has the light transmittance higher than that of the reflection/transmission film, and the reflection/transmission film has a light reflectance higher than that of the first transmission film and lower than that of the light blocking film.

Abstract: An electronic device includes a first display panel including a first display surface, and a second display panel including a second display surface and configured to be disposed such that light emitted from the first display surface is incident on the second display surface. The first display panel is configured such that light emitted from the first display surface and incident on the second display surface includes a large amount of P-polarization components. The second display panel is a reflection-type display panel, and includes a polarizer disposed on the second display surface and configured to absorb S-polarization components of incident light.
