Abstract

A display panel includes: a panel section including a display region where a plurality of pixels are arranged, and a gap region provided in a gap between the pixels; and a barrier section including a plurality of transmissive regions in a two-dimensional arrangement, and a light-blocking region to be around each of the transmissive regions. The transmissive regions are each configured to make entirely visible any one of the pixels therethrough when a viewer views the panel section not from a front but from a first or second direction via the barrier section, the pixels are each configured by a plurality of sub-pixels varying in type, and the sub-pixels in each of the pixels are arranged not in stripes but differently.

Claims (39)

1. A display panel, comprising:

a panel section including a display region where a plurality of pixels are arranged, and a light-blocking section provided in a gap between the pixels; and

a barrier section including a plurality of transmissive regions in a two-dimensional arrangement, and a light-blocking region around each of the transmissive regions,

wherein,

the transmissive regions are each configured to make entirely visible any one of the pixels therethrough when a viewer views the panel section not from a front but from a first or second direction via the barrier section,

each of the pixels comprises a plurality of sub-pixels of different types,

the sub-pixels in each of the pixels are arranged other than in stripes,

the pixels include a plurality of first pixels and a plurality of second pixels, the first pixels being visible through the transmissive regions when viewed from the first direction and the second pixels being visible through the transmissive regions when viewed from the second direction,

in two of the first pixels adjacent to each other in a vertical or diagonal direction, the sub-pixels are laid out differently,

in two of the second pixels adjacent to each other in the vertical or diagonal direction, the sub-pixels are laid out differently, and

the light-blocking section includes a first light-blocking section whose area is substantially equal to an area of one of the pixels, and a second light-blocking section whose area is smaller than an area of the first light-blocking section.

2. The display panel according to claim 1 , wherein the first and second pixels are arranged alternately in a two-dimensional plane.

3. The display panel according to claim 1 , wherein the first and second light-blocking sections are arranged alternately in a two-dimensional plane.

4. The display panel according to claim 3 , wherein the first and second light-blocking sections are alternately arranged in a lateral direction with one of the pixels sandwiched therebetween.

5. The display panel according to claim 4 , wherein the transmissive regions are each provided at a position corresponding to the first light-blocking section.

6. A display device, comprising:

a panel section including a display region where a plurality of pixels are arranged, and a light-blocking section provided in a gap between the pixels;

a barrier section including a plurality of transmissive regions in a two-dimensional arrangement, and a light-blocking region around each of the transmissive regions; and

a drive section driving the panel section or both the panel section and the barrier section,

wherein,

the transmissive regions are each of a size allowing viewing of any one of the pixels entirely therethrough when a viewer views the panel section not from a front but from a first or second direction via the barrier section,

each of the pixels comprises a plurality of sub-pixels of different types,

the sub-pixels in each of the pixels are arranged other than in stripes,

the pixels include a plurality of first pixels and a plurality of second pixels, the first pixels being visible through the transmissive regions when viewed from the first direction, and the second pixels being visible through the transmissive regions when viewed from the second direction,

in two of the first pixels adjacent to each other in a vertical or diagonal direction, the sub-pixels are laid out differently,

in two of the second pixels adjacent to each other in the vertical or diagonal direction, the sub-pixels are laid out differently, and

the light-blocking section includes a first light-blocking section whose area is substantially equal to an area of one of the pixels, and a second light-blocking section whose area is smaller than an area of the first light-blocking section.

7. An electronic unit with a display device, the display device comprising:

a panel section including a display region where a plurality of pixels are arranged, and a light-blocking section provided in a gap between the pixels;

a barrier section including a plurality of transmissive regions in a two-dimensional arrangement, and a light-blocking region to be around each of the transmissive regions; and

a drive section driving the panel section or both the panel section and the barrier section,

wherein,

the transmissive regions are each configured to make entirely visible any one of the pixels therethrough when a viewer views the panel section not from a front but from a first or second direction via the barrier section,

each of the pixels comprises a plurality of sub-pixels of different types,

the sub-pixels in each of the pixels are arranged other than in stripes,

the pixels include a plurality of first pixels and a plurality of second pixels, the first pixels being visible through the transmissive regions when viewed from the first direction, and the second pixels being visible through the transmissive regions when viewed from the second direction,

in two of the first pixels adjacent to each other in a vertical or diagonal direction, the sub-pixels are laid out differently,

in two of the second pixels adjacent to each other in the vertical or diagonal direction, the sub-pixels are laid out differently, and

the light-blocking section includes a first light-blocking section whose area is substantially equal to an area of one of the pixels, and a second light-blocking section whose area is smaller than an area of the first light-blocking section.
