Abstract:
Regarding a flexible display apparatus, a technique capable of securing connection performance between the members in the thickness direction and reducing the change of the cell gap, and besides, achieving favorable optical property such as the improvement of the aperture ratio is provided. A display apparatus 1 includes: a first substrate SB1 having flexibility; a second substrate SB2 having flexibility; a liquid crystal layer LQ serving as an electrooptic layer; and a display area made of these components. The second substrate SB2 includes: a color filter (second color filter CF2) arranged in a region corresponding to an opening P1 of each pixel in the display area in a plan view; and a first light blocking film BM1 having an ultraviolet-light transmitting property and arranged in a region corresponding to a non-opening P2 between pixels. The electrooptic layer includes a polymer wall PW arranged in a region overlapping the first light blocking film BM1 in a plan view, the region overlapping this film, and connecting a surface Sf11 of the first substrate SB1 and a surface Sf22 of the second substrate SB2.
