PURPOSE:To equalize the light quantity distribution without decreasing the absolute transmissive light quantity by forming a microlens body like an array on this side of a liquid crystal opening part so as to form a rough focus in each liquid crystal opening part and providing a lens array body for varying separately a condensing characteristic of the microlens body. CONSTITUTION:A microlens 102 is attached so as to form a rough focus in each liquid crystal picture element opening part 107 of a liquid crystal display element, and a characteristic (for instance, a converging function) of the microlens 102 is made so as to correct the ununiformity of a luminous flux of a light source. That is, in a liquid crystal display position, in a part in which the incident luminous flux quantity is small (a peripheral part of the liquid crystal display element), a lens having a large condensing property (a lens having the maximum diameter that can be taken in a pitch of a picture element) is built in, and in a part in which the incident light quantity is large (the center part of the liquid crystal display element), a lens whose condensing property is relatively smaller than the lens having a large condensing property is built in. In such a way, the luminous flux quantity for transmitting through the liquid crystal display element, and also, the luminous flux quantity for reaching a screen can be uniform. |
