Liquid crystal display and electronic apparatus

Abstract

The present invention provides a color transflective liquid crystal display that is capable of display with good coloring and high visibility in both a reflective mode and a transmissive mode while suppressing deterioration in color reproduction caused by unevenness of the spectral properties of the illumination light, if any. The liquid crystal display can include a liquid crystal display panel including pixels formed of a plurality of sub-pixels each corresponding to different colors, and an illumination device, wherein the liquid crystal display panel includes a transflective layer and a color filter of color corresponding to each of the sub-pixels. The transflective layer includes transmissive portions for transmitting illumination light, wherein the transmissive portion is formed such that the dimension of the transmissive area corresponding to the transmissive portion of at least one sub-pixel out of the plurality of sub-pixels and the dimension of the transmissive area corresponding to the transmissive portion of another sub-pixel, differ.

What is claimed is:  
     
         1 . A liquid crystal display, comprising: 
 a liquid crystal display panel formed of liquid crystals sandwiched between a pair of opposing substrates, and including pixels having a plurality of sub-pixels each corresponding to different colors;    an illumination device provided to an opposite side of the liquid crystal display panel in relation to an observation side that illuminates the liquid crystal display panel with illumination light;    a transflective layer disposed on the opposite side of the liquid crystals in relation to the observation side with a transmissive portion that transmits the illumination light formed thereto, the transmissive portion being formed such that a first dimension of a transmissive area corresponding to the transmissive portion of least at one sub-pixel out of the plurality of sub-pixels and a second dimension of a transmissive area corresponding to the transmissive portion at another sub-pixel, differ; and    a color filter provided corresponding to each of the sub-pixels that transmits light of a wavelength corresponding to a color of each sub-pixel.    
     
     
         2 . The liquid crystal display according to  claim 1 , the dimension of the transmissive area at each sub-pixel being a dimension according to spectral properties of the illumination light.  
     
     
         3 . The liquid crystal display according to  claim 2 , the dimension of the transmissive area at each sub-pixel being a dimension according to the luminance of a wavelength of the illumination light corresponding to a color of the sub-pixel.  
     
     
         4 . The liquid crystal display according to  claim 3 , the dimension of the transmissive area at a sub-pixel of a color corresponding to a wavelength of the illumination light with great luminance being smaller than the dimension of the transmissive area at a sub-pixel of a color corresponding to a wavelength of the illumination light with small luminance.  
     
     
         5 . The liquid crystal display according to of  claim 1 , the dimension of the transmissive area at each of the sub-pixels differs for each sub-pixel corresponding to a different color.  
     
     
         6 . The liquid crystal display according to  claim 1 , the dimension of the transmissive area at each of the sub-pixels differing according to a position of the sub-pixel within a substrate face of the liquid crystal display panel.  
     
     
         7 . The liquid crystal display according to  claim 1 , the transmissive portion being an opening portion formed in the transflective layer corresponding to each of the sub-pixels.  
     
     
         8 . The liquid crystal display according to  claim 7 , the opening portion comprising opening parts of generally the same dimension that are formed mutually separated for the number according to the dimension of the transmissive area at the sub-pixels.  
     
     
         9 . The liquid crystal display according to  claim 1 , the transflective layer having the transmissive portion formed such that an area along at least one side of a plurality of sides defining each sub-pixel serves as the transmissive area.
