Display panel

Abstract

To prevent the display quality from being degraded as a result of (i) a boundary portion of an edge region of the display region being visibly in the shape of stairs and/or (ii) emitted light having an unintended color, a display panel includes a light-shielding section including, for each pixel ( 5 ) through which a curved boundary line (ideal line) extends, sub-pixel light-shielding sections ( 3 a ) each overlapping a corresponding one of a red sub-pixel ( 4 R), a green sub-pixel ( 4 G), and a blue sub-pixel ( 4 B).

1 - 8 . (canceled) 
     
     
         9 : A display panel, comprising:
 a display region in which a plurality of pixels are present, each of the plurality of pixels includes a first sub-pixel, a second sub-pixel, and a third sub-pixel adjacent to one another; and   a light shield that shields at least a portion of an edge region of the display region from light, wherein   the light shield includes, for each pixel among the plurality of pixels through which pixel a boundary line in a curve between the light shield and a side of a center of the display region extends, sub-pixel light shields that each overlap a corresponding one of the first sub-pixel, the second sub-pixel, and the third sub-pixel, and   the sub-pixel light shield is sized such that a ratio of respective openings of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel among the plurality of pixels through which pixel the boundary line extends is equal to a ratio of respective openings of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel among the plurality of pixels through which pixel the boundary line does not extend and that a ratio of an area of a portion of each pixel among the plurality of pixels through which pixel the boundary line extends at which portion the light shield is absent to an area of the each pixel among the plurality of pixels through which pixel the boundary line extends is equal to a ratio of an area of an opening of one of the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel among the plurality of pixels through which pixel the boundary line extends to an area of an opening of a corresponding sub-pixel among the first sub-pixel, the second sub-pixel, and the third sub-pixel of each pixel among the plurality of pixels through which pixel the boundary line does not extend.   
     
     
         10 : The display panel according to  claim 9 , wherein
 the first sub-pixel, the second sub-pixel, and the third sub-pixel each have a length in a first direction and a length in a second direction orthogonal to the first direction, the length in the first direction being longer than the length in the second direction, and   the sub-pixel light shields have an equal length in the second direction and are each sized on a basis of a length of the sub-pixel light shield in the first direction.   
     
     
         11 : The display panel according to  claim 9 , wherein
 the first sub-pixel, the second sub-pixel, and the third sub-pixel each have a length in a first direction and a length in a second direction orthogonal to the first direction, the length in the first direction being longer than the length in the second direction, and   the sub-pixel light shields have an equal length in the first direction and are each sized on a basis of a length of the sub-pixel light shield in the second direction.   
     
     
         12 : The display panel according to  claim 9 , wherein
 the sub-pixel light shield each include a plurality of openings and are each sized on a basis of the plurality of openings.   
     
     
         13 : The display panel according to  claim 9 , wherein
 the sub-pixel light shields each include an opening at a central portion of the corresponding one of the first sub-pixel, the second sub-pixel, and the third sub-pixel.   
     
     
         14 : The display panel according to  claim 12 , wherein
 the plurality of openings are present at only a portion of the corresponding one of the first sub-pixel, the second sub-pixel, and the third sub-pixel.   
     
     
         15 : The display panel according to  claim 9 , wherein
 the first sub-pixel, the second sub-pixel, and the third sub-pixel each include a liquid crystal layer.   
     
     
         16 : The display panel according to  claim 9 , wherein
 the first sub-pixel, the second sub-pixel, and the third sub-pixel each include a light-emitting layer.
