A display, comprising:

• a light source;
• an LCD panel;
• and
• a polarizer, disposed between said light source and said LCD panel;
• wherein said polarizer comprises a polymeric continuous phase and a disperse phase, disposed within said continuous phase, and wherein said display exhibits a relative gain as a function of angle within the range of 30.degree. to 60.degree..

A display, comprising:

• a light source;
• an LCD panel;
• and
• a polarizer, disposed between said light source and said LCD panel;
• wherein said polarizer comprises a polymeric continuous phase and a disperse phase, disposed within said continuous phase, and wherein the average of the relative gain for said display taken over the range of 30.degree. to 60.degree. is greater than the relative gain of said display at normal incidence.

A display, comprising:

• an LCD panel;
• and
• a polarizer, disposed between said light source and said LCD panel;
• wherein said polarizer comprises a birefringent polymeric continuous phase and a disperse phase, disposed within said continuous phase, wherein said display exhibits a maximum relative gain as a function of angle within the range of 30.degree. to 60.degree., and wherein said polarizer has a total diffuse reflectivity of at least about 30%.

A display, comprising:

• a display module;
• a light source adapted to illuminate the display module;
• and
• a polarizer, positioned between the display module and the light source, said polarizer being adapted to transmit toward the display module light from the light source which has a first polarization orientation, and being further adapted to reflect away from the display module light from the light source which has a second polarization orientation;
• wherein the polarizer comprises a polymeric continuous phase and a disperse phase, disposed within said continuous phase, and wherein said display exhibits a relative gain at 60.degree. that is at least equal to the relative gain exhibited by said display at normal incidence.
