Display device and method of manufacturing the same

A method of manufacturing a display device, comprising the steps of:

• providing an optical layer on a display panel;
• providing a window on the optical layer;
• and
• providing a light control layer between the display panel and the optical layer or between the optical layer and the window, wherein providing the light control layer comprises:
• coating an inorganic material on a preliminary transmission portion;
• etching the inorganic material to form a mask;
• etching the preliminary transmission portion to form a plurality of transmission portions spaced apart from each other;
• forming a preliminary light blocking portion on the mask and between the transmission portions;
• and
• removing the mask wherein a light blocking portion is formed, wherein a thickness (T0) of each of the transmission portions and a width (S0) of each of the transmission portions in a cross-section are determined by a function of

A display device, comprising:

• a display panel;
• and
• a light control layer disposed on the display panel,
• wherein the light control layer comprises:
• a plurality of transmission portions spaced apart from each other and a light blocking portion between the transmission portions, wherein a ratio of a thickness of each of the transmission portions and a width of each of the transmission portions in a cross-section is a function of a refractive index of the transmission portions and an exit angle of light emitted from the display panel and propagating through the light control layer, wherein the refractive index of the transmission portions is equal to or greater than about 1.4 and equal to or less than about 1.7, and the exit angle is equal to or greater than about 30° and equal to or less than about 50°.
