Provided are a display device and a display unit having higher light extraction efficiency. An optical distance L<SUB>1 </SUB>between a maximum light-emitting position of a light-emitting layer and a first end portion satisfies L<SUB>1</SUB>=tL<SUB>1</SUB>+a<SUB>1 </SUB>and (2tL<SUB>1</SUB>)/lambda=-Phi<SUB>1</SUB>/(2pi)+m<SUB>1</SUB>. An optical distance L<SUB>2 </SUB>between the maximum light-emitting position and a second end portion satisfies L<SUB>2</SUB>=tL<SUB>2</SUB>+a<SUB>2 </SUB>and (2tL<SUB>2</SUB>)/lambda=-Phi<SUB>2</SUB>/(2pi)+m<SUB>2</SUB>. In the formulas, tL<SUB>1 </SUB>and tL<SUB>2 </SUB>represent a theoretical optical distance between the first end portion and the maximum light-emitting position and a theoretical optical distance between the second end portion and the maximum light-emitting position, respectively, a<SUB>1 </SUB>and a<SUB>2 </SUB>represent correction amounts based upon a light-emitting distribution in the light-emitting layer, lambda represents a peak wavelength of the spectrum of light desired to be extracted, Phi<SUB>1 </SUB>and Phi<SUB>2 </SUB>represent a phase shift of reflected light generated in the first end portion and a phase shift of reflected light generated in the second end portion, respectively, and each of m<SUB>1 </SUB>and m<SUB>2 </SUB>is 0 or an integer.
